Companion Diagnostics GenDx

In the world of transplantation and clinical immunology, HLA (Human Leukocyte Antigen) typing is the ultimate “barcode” of human identity. It is the system our bodies use to differentiate “self” from “non-self.” Because this system is the most diverse part of the human genome, we need a naming convention that is as precise as the DNA itself.

With thousands of new alleles discovered every year, scientists rely on a standardized nomenclature, a biological “IP address” that allows clinicians and researchers worldwide to speak the exact same language.

The anatomy of an allele name

The length of an allele’s name is determined by its unique sequence and how closely it resembles its nearest known relative. While every allele is assigned at least a four-digit designation (covering the first two fields), additional digits are added when further genetic distinction is required.

At first glance, an HLA designation like HLA-DRB1*13:01:01:02N looks like a complex string of random characters. In reality, it is a highly structured map.

Here is how to read it:

1. The prefix and gene (HLA-DRB1)

Before the asterisk, we identify the specific “location” the gene lives in.

• HLA: The region.

• DRB1: The specific locus (location) on the chromosome.

2. The first field: The type (*13)

The digits before the first colon usually describe the serological type. This is a callback to the old days* of “low resolution” typing. If you were an HLA specialist in the 1980s, you would recognize “13” as the DR13 antigen. It’s the broad family name.

3. The second field: The subtype (:01)

Now we get into the proteins. If two alleles have different numbers in this field (e.g., :01 vs :02), it means there is a change in the amino acid sequence. For the specialist, this is the most critical field for transplantation, as changes here can alter the shape of the peptide-binding groove, potentially triggering an immune response.

4. The third field: Silent substitutions (:01)

Sometimes, DNA changes but the protein stays exactly the same. These are called synonymous or “silent” mutations.

• Why it matters: Even if the protein doesn’t change, these variations help researchers track human migration and genetic evolution.

5. The fourth field: The non-coding regions (:02)

This field looks at the “dark matter” of the gene, the introns or the flanking regions (5’ and 3’ UTRs). These are areas of the DNA that aren’t turned into protein but might affect how much of the protein is made.

The “special suffixes”: Nature’s plot twists

Sometimes, a gene is present but it doesn’t behave. This is where the letter at the end comes in. Think of these as the “status updates” of the HLA world:

• N (Null): The “Ghost” allele. The DNA is there, but no protein is expressed. In a transplant, an “N” allele is effectively invisible to the immune system.

• L (Low): The “Quiet” allele. The protein reaches the cell surface, but in significantly lower amounts than normal.

• S (Secreted): The “Rule-Breaker.” Instead of sitting on the cell surface like a flag, this protein is shed and found floating freely in fluids.

• Q (Questionable): The “Mystery.” A mutation exists that usually messes up expression in other genes, but we haven’t confirmed exactly what it’s doing here yet.

*Why not just use old names?

Before 2010, the naming system didn’t use colons, which led to a “naming ceiling.” As we discovered more than 99 subtypes for a single group, we ran out of numbers! The modern colon-delimited system provides an infinite runway for future discoveries.

Want to dive deeper into the latest allele updates? Check out the IPD-IMGT/HLA Database for a full list of the thousands of alleles currently recognized by the World Health Organization (WHO) Nomenclature Committee.

𝗔𝗯𝗼𝘂𝘁 𝘄𝗲𝗯𝗶𝗻𝗮𝗿
Within the field of solid organ transplantation, HLA molecular matching is a hot topic. Over the past decade, multiple approaches have been introduced to predict HLA immunogenicity on the molecular level.

While, indeed, at the population level, an increasing number of molecular mismatches is strongly associated with the formation of de novo donor-specific antibody and worse graft survival after transplantation, at the patient level, it is not necessarily a numbers game. Not every HLA molecular mismatch is equally immunogenic, and immunological risk assessments require more than counting mismatches.

We are happy to announce that on February 26-28, 2026, GenDx will be present at EWIC conference in Zagreb, Croatia.

When an organ becomes available, transplant teams are under pressure to act fast, but accuracy in matching is equally critical. Today, most deceased donor HLA typing is still performed at intermediate resolution, which can limit certainty when ruling out donor-specific antibodies (DSAs). As a result, the ability to use virtual crossmatching may be restricted, ultimately slowing down organ allocation for highly-sensitised recipients. Rapid high-resolution typing could be the solution to these limitations.

High-resolution typing across HLA loci could help overcome this challenge by bringing typing resolution in line with how HLA antibodies are defined. If performed quickly enough, rapid high-resolution typing could support more confident decision-making and improve the chance that suitable organs are accepted in time.

In our upcoming webinar, Lizzy Russell-Lowe, Clinical Scientist at Manchester Royal Infirmary, will present a study in which HLA typing results obtained with the GenDx NGS-Turbo® kit, using Oxford Nanopore Technologies sequencing, were retrospectively compared with standard intermediate-resolution HLA typing methods. The NGS-Turbo^® kit produced concordant typing results for all samples in less than 4 hours, showcasing the potential of rapid high-resolution typing.

• Can rapid high-resolution typing be delivered fast enough for deceased donor timelines?

• Could it help reduce reliance on wet crossmatching?

• What might the potential benefits be for highly-sensitised patients?

The promising results of the study will be discussed in detail during our upcoming webinar, highlighting the advantages of rapid high-resolution typing:

In September, the month of the World Marrow Donor Day, GenDx organized their ‘Fit to Donate’ initiative.

Since 2018, GenDx has partnered with Matchis, the Dutch Center for Stem Cell Donors. The goal is to raise awareness about stem cell transplantation among young, healthy potential donors in and around Utrecht. This aligns with GenDx’s mission to improve the quality of life and survival chances of transplant patients. This year, the focus shifted to raising funds for Matchis.

You probably heard on the news that there is a need for more potential stem cell donors. This increases the chances of finding a life-saving match for all patients needing a stem cell transplant. Each new donation represents hope to get a second chance at life.

Did you know that it costs Matchis €35,- to type and register one single potential stem cell donor in the international database? With an aimed growth of 20,000 new registrations per year, this represents a significant expense. To cover these costs, Matchis largely relies on sponsorships and donations. That’s why GenDx decided to start a campaign on SterkvoorMatchis.nl, Matchis’ fundraising platform.

To support this ‘Sterk voor Matchis’ campaign, GenDx organized the ‘Fit to Donate’ initiative during the month of September. This culminated in the ‘GenDx Tulip Run’ on September 23. Inspired by previous “Tulip Runs” held during Immunogenetics conferences, this event brought together GenDx colleagues, friends, and family. Everyone was motivated to run or walk at Utrecht Science Park by a shared goal.

Our colleagues really went the extra mile in September. We look back on an amazing day filled with teamwork, laughter and a healthy sense of competitiveness. We raised an impressive € 3.850,- for Matchis – symbolizing one newly registered stem cell donor for each GenDx employee.

Lunch Symposium | Tuesday, March 25

This year, we celebrate 20 years of GenDx and two decades of dedication to transplant diagnostics. What began as a small team of scientists with a shared vision has grown into a globally recognized leader, driven by innovation, collaboration, and a commitment to improving the quality of life and survival of transplant patients.

The beginning

On January 1st, 2004, Erik Rozemuller and Wietse Mulder began shaping Genome Diagnostics. After a year of planning, GenDx was officially established on March 1st, 2005. We started as a small team of dedicated scientists working to develop better tools for high-resolution HLA typing. From the beginning, collaboration and education were as important to us as innovation. We knew that true progress in transplantation wouldn’t come from technology alone but also from sharing knowledge with the healthcare professionals who rely on it every day.

Growing with purpose

Over the years, GenDx has evolved, but our core mission has remained the same. In 2013, we introduced NGSgo reagents and NGSengine software, making high-resolution sequencing for HLA typing more accessible to labs worldwide. As our expertise grew, we expanded our focus to include chimerism monitoring with NGStrack and TRKengine, helping transplant teams detect complications earlier.

In 2022, we became part of Eurobio Scientific, a step that allowed us to strengthen our impact globally while remaining true to our values. Today, we are proud to be part of a broader network of diagnostics specialists, with affiliates across Europe and other parts of the world.

A global leader in transplant diagnostics

GenDx is one of the top tier companies in transplant diagnostics worldwide, recognized for our commitment to research, education, and high-quality solutions. We have grown into a team of over 110 colleagues from 20 different nationalities, bringing diverse perspectives and expertise to our work. This would not be possible without the support and commitment from our customers and partners. Today, we collaborate with 40 distributors worldwide and are able to reach hospitals and research centres around the globe.

A few words from our General Manager

“GenDx remains dedicated to advancing the field of transplant diagnostics, building on 20 years of progress. With our talented team and strong partnerships, we are committed to continuing our efforts to improve patient outcomes and make meaningful contributions to the broader transplant community and the Eurobio Scientific Group.”
– Maarten Penning, PhD, General Manager

Lunch Symposium | Wednesday, February 5

In 2024, one of GenDx’s key objectives was to reduce our environmental impact. To bring this vision to life, a group of seven enthusiastic colleagues came together to form the Sustainability Group. This team is dedicated to identifying opportunities, implementing changes, and inspiring our entire company to contribute to a greener future.

How Sustainability at GenDx Started

Our journey toward sustainability began as a colleague-driven initiative. The growing global focus on environmental issues inspired us to take action. This is a problem that can no longer be ignored, so we set some initial goals, milestones, and formed a dedicated group to make it happen. Today, the Sustainability Group works to implement sustainable practices and track their progress, while also raising awareness across the company.

What Sustainability Means for GenDx
For us, sustainability is not just about “going green.” It’s about taking measurable steps to ensure our operations have a minimal environmental footprint, both in and out of the lab. It’s about finding innovative ways to balance quality with eco-consciousness, inspiring others, and making a meaningful impact on the world.

GenDx’s Green Initiatives
We are proud to share some of the steps we’ve taken so far:
-Reducing Styrofoam usage. We’ve cut down our reliance on Styrofoam shipping boxes by 80%.
-Minimizing paper waste. By switching to digital signatures, reusable notebooks, and reducing printed materials like business cards, we’re cutting back significantly. We’ve even started -tracking printing habits to better understand our usage.
-Recycling gloves. Through the Kimberly-Clark Professional RightCycle program, we aim to recycle 90% of our lab gloves.

Why Sustainability Matters
Sustainability holds deep personal meaning for many of us at GenDx. Reflecting on years spent in the lab, one colleague shared: “After years of working in labs, I’ve seen how wasteful the work can be—especially with single-use plastics. I’ve always thought about how we could reduce waste while still maintaining the quality of our work. It’s exciting to see new alternatives, like greener plastics, emerging. Now, it’s all about researching and figuring out what solutions work best for us..”

Simple Sustainable Habits
We believe that even small daily actions can contribute to a larger shift. Some of the habits our team members practice include:
-Shopping at local zero-waste stores with reusable containers.
-Using reusable bags and water bottles.
-Composting food waste and recycling.
-Traveling by bike or public transport whenever possible.

Looking Forward to 2025
At GenDx, we are constantly looking for ways to improve and reduce our environmental footprint. Whether it’s through big company-wide changes or individual habits, we’re committed to making a positive impact.

Rebrand to reflect growth, innovation, and a unified vision

Utrecht, 11 November 2024

We are happy to announce that GenDx will undertake a brand update to align with the evolving structure of the Eurobio Scientific Group.

This new brand embodies the collective strengths of all our affiliates, combining expertise and resources to create synergies to enhance our product offerings. Furthermore, our collaboration will allow us to drive innovation through sharing knowledge, ensuring that we deliver innovative products and services that are at the forefront of the diagnostics field. And while our brand is evolving, our commitment to do so remains our top priority.

Denis Fortier, CEO & Chairman of Eurobio Scientifics Executive Committee, states: “This rebranding reflects who we are, our evolution as a larger group, representing growth, innovation, and a unified vision to become a leading global Specialty Diagnostics company offering highly innovative solutions. Our mission remains the same: Lead breakthrough innovation in the fields of infectious diseases, transplantation & oncology by developing and supporting a comprehensive portfolio of molecular diagnostics technologies encompassing our own solutions and those of our partners. ”

Why is the brand changing?

We are transitioning to a new brand identity that reflects the integration of all affiliates within the Eurobio Scientific Group. This means our visual identity will be updated to ensure consistency and foster harmony among the group’s companies.

What is changing?

We will have a new brand that reflects consistency across the Eurobio group companies, this means an update to our logo, icon, typography, form elements and color scheme.

Logo: We now have a logo that is part of a cohesive logo family while maintaining similar color schemes to what it is familiar to us. The GenDx logo consists of two parts: “Eurobio’’ as the main family name, followed by the name of the family member “GenDx’’.

Icon: All company divisions now share a distinctive brand icon, which serves as a unifying element for the Eurobio Group’s identity. Each affiliate uses the icon with their own color palettes.

Product packaging, labels, and documentation: We will gradually update all product packaging, labels, and documents to align with the new branding. During this transition, you may encounter both the old and new branding until all materials are fully updated. Please note that the content itself will remain unchanged.

Products & Services: There will be no changes to our products and services. Our dedicated team, high-quality products, and services will remain the same.

Sustainable rebranding

The rebranding process will unfold over the coming months, focusing on minimizing waste. By reusing materials such as product boxes, brochures, and exhibition booths, we aim to ensure an environmentally friendly transition. As a result, you may still see our old branding during the transition period.

Thoughts from leadership:

“What I like a lot about the branding is that it unifies the group, but it also gives every company their unique color.’’ Hanneke Merkens, Eurobio Chief Marketing Officer says “So the Eurobio as a group is blue and GenDx remains purple. DID is red, TECOmedical and BMD have their own shade of blue. That’s what I like a lot because it gives every individual affiliate their own identity and still keeps as a part of the group. We share the same font, the same logo, and we also share the same icon. And especially the icon is a nice visual, created to make sure that everyone recognizes us as Eurobio Group while we keep our own identity.’’

“I see an exciting future for Eurobio Scientific as a group.’’ Maarten Penning, GenDx General Manager, and Eurobio Chief Technology Officer added “We have combined our strengths in research and development, software development, marketing, customer support, sales, and all associated service and support, efforts. So in this new constellation, I am confident that we can keep on developing new innovative products that will be of benefit to patients worldwide, that we can grow as a company and develop multiple innovative diagnostic solutions.”

We look forward to embarking on this new phase of our visual identity together with you and strengthening our commitment to advancing the field of transplantation.

PRESS RELEASE

Utrecht, May 25, 2023

GenDx has obtained a worldwide license from Università degli Studi di Torino (UNITO) for their method to detect donor specific cell free DNA (cfDNA) in patients that have undergone a lung transplant.
To monitor graft survival, patients typically need bronchoscopy or lung biopsies that are invasive, require anaesthesia and are risky. Moreover, these methods suffer from interobserver variability and are expensive. Researchers at UNITO developed a method that instead requires only a blood sample to monitor transplant rejection. The method comprises a sensitive digital droplet PCR assessment of the cfDNA donor fraction and is superior to biopsies in terms of costs, turnaround time and level of sensitivity. The assay, although developed for lung transplant patients, opens a door for broader solid organ transplants as it supports a pan-organ strategy.
This UNITO license broadens the licence agreement that was obtained earlier from Medical College Wisconsin for its method to detect cfDNA in paediatric patients that have undergone a heart transplant.

Wietse Mulder PhD, CEO of GenDx, commented: “Combining the knowledge of both UNITO on cfDNA and GenDx on DNA typing by NGS and real-time PCR in a transplant setting, offers an enormous potential to develop products which can predict early the potential rejection of transplanted organs. We are excited to collaborate with UNITO enabling new options for accurate transplant monitoring”

Statement UNITO, said: “We are glad to start this new collaboration with GenDx and excited to see that a research idea from our group can move forward and hopefully become a kit. Our goal now is to go on with the necessary steps to optimize our method to fit it in a box and validate it in larger cohorts of patients, working in close collaboration with a company that is a leader in the field of molecular diagnostics for transplantation.”

About Cell free DNA
Donor derived cfDNA refers to all non-encapsulated DNA fragments that enter the bloodstream; this mostly happens during apoptosis or necrosis. Analysis of cell free DNA (cfDNA) after solid organ transplantation has been shown to accurately identify and characterize allograft injury and correlate with pathologic findings (e.g. organ rejection).

About the UNITO
The University of Torino (UniTo) in north-west Italy is one of the country’s largest and most prestigious universities. Founded in 1404, UniTo provides quality higher education and research opportunities; many UniTo graduates have achieved international renown. Today, the University of Torino offers over 150 undergraduate and graduate degree programs in almost every field of study. A growing number of programs are taught in English, and Italian language tuition is available for incoming students. The University’s 27 departments offer excellent opportunities for Italian and non-Italian academic staff; doctoral school provides more than 30 doctoral programs.

About Eurobio Scientific
Eurobio Scientific is a key player in the field of specialty in vitro diagnostics. It is involved from research to manufacturing and commercialization of diagnostic tests in the fields of transplantation, immunology and infectious diseases, and sells instruments and products for research laboratories, including biotechnology and pharmaceutical companies.

PRESS RELEASE

NGS-Turbo® is a novel rapid high-resolution HLA typing kit aimed at improving transplant outcomes

GenDx today announces that it has signed a non-exclusive service agreement with Oxford Nanopore Technologies (Oxford Nanopore). The agreement aims to bring its new NGS-Turbo® product to the transplant market for high-resolution HLA typing. This is achieved with a turnaround time of less than four hours. It is crucial to enable improved matching of solid organs in situations where time is a critical factor.
Organ transplantation requires a solid donor organ to be matched to a recipient. Due to time constraints, HLA typing of solid organs such as kidneys is typically restricted to low-resolution results. Nanopore technology allows for high-resolution sequencing in a time frame suitable for critical organ transplantations. The agreement between GenDx and Oxford Nanopore lifts the 48-hour data processing restriction for commercial software. NGS-Turbo® users can deliver high-resolution HLA typing results to the clinic within four hours after receiving the sample. This contributes to better organ matching and facilitates a better transplantation outcome.

Wietse Mulder PhD, CEO of GenDx, commented: “We are happy that we were able to come to an agreement with Oxford Nanopore. By combining our expertise as a world leader in sequencing-based HLA typing with the sequencing knowledge of Oxford Nanopore, we are convinced that we will be able to bring products to the organ transplantation field. These products will allow better HLA typing, enabling better matching and improved outcome of transplantation.”

About NGS-Turbo®
NGS-Turbo® is one of the latest developments by GenDx. An early access program will start later this year. It consists of a fast amplification of all 11 HLA loci using a whole-gene approach with NGS-Turbo®Amp. After the subsequent extremely quick library preparation NGS-Turbo®Prep, a sample can be sequenced on Oxford Nanopore sequencers. The data can be directly analyzed and typed with NGSengine®. NGS-Turbo is an expansion of GenDx’ current high-resolution HLA typing portfolio.

About Oxford Nanopore Technologies
Oxford Nanopore Technologies’ goal is to bring the widest benefits to society. They aim for enabling the analysis of anything, by anyone, anywhere. The company has developed a new generation of nanopore-based sensing technology. This allows real-time, high-performance, accessible, and scalable analysis of DNA and RNA. The technology is used in more than 120 countries to understand the biology of humans and diseases such as cancer, plants, animals, bacteria, viruses and whole environments. Oxford Nanopore Technologies products are intended for molecular biology applications. However, they are not intended for diagnostic purposes.

PRESS RELEASE

GenDx has obtained a worldwide license from Medical College Wisconsin (MCW) for their patented method to detect donor specific cell free DNA (cfDNA) in pediatric patients that have undergone a heart transplant.

To monitor graft survival, patients need multiple endomyocardial biopsies that are expensive, require anesthesia and are invasive and risky. Researchers at MCW developed a method that instead requires only a small blood sample to monitor transplant rejection. The method comprises a sensitive multiplexed qPCR assessment of the cfDNA donor fraction, which is superior in terms of costs, turn-around time and level of sensitivity. The assay, although developed for pediatric transplant patients, opens a door for broader solid organ transplants as it supports a pan-organ strategy.

Wietse Mulder PhD, CEO of GenDx, commented: “Combining the knowledge of both MCW on cfDNA and GenDx on DNA typing by NGS and real-time PCR in a transplant setting, offers an enormous potential to develop products which can predict early the potential rejection of transplanted organs. We are excited to collaborate with MCW enabling new options for accurate transplant monitoring,”

About Cell free DNA

Donor derived cfDNA refers to all non-encapsulated DNA fragments that enter the bloodstream; this mostly happens during apoptosis or necrosis. Analysis of cell free DNA (cfDNA) after solid organ transplantation has been shown to accurately identify and characterize allograft injury and correlate with pathologic findings (e.g. organ rejection).

About the Medical College of Wisconsin

With a history dating back to 1893, The Medical College of Wisconsin is dedicated to leadership and excellence in education, patient care, research and community engagement. More than 1,500 students are enrolled in MCW’s medical school and graduate school programs in Milwaukee, Green Bay, and Central Wisconsin. MCW’s School of Pharmacy graduated its inaugural PharmD class in 2020. A major national research center, MCW is the largest research institution in the Milwaukee metro area and second largest in Wisconsin. In the last 10 years, faculty received more than $1.5 billion in external support for research, teaching, training and related purposes. This total includes highly competitive research and training awards from the National Institutes of Health (NIH). Annually, MCW faculty direct or collaborate on more than 3,100 research studies, including clinical trials. Additionally, more than 1,650 physicians provide care in virtually every specialty of medicine for more than 2.8 million patients annually.

GenDx obtains a license for haplotyping within transplant diagnostics from Dovetail Genomics

PRESS RELEASE

UTRECHT, June 2 2022
GenDx has obtained a license from Dovetail Genomics to further develop their Micro-C proximity ligation assay. This modern technology will be a new step improving precision to haplotyping of HLA genes. And, as targeted DNA capture is part of the assay, GenDx will combine this methodology with its extensive knowledge of next-generation sequencing (NGS)-based HLA typing. This will help to develop highly attractive products.

HLA typing is a method to determine donor and recipient compatibility. It is essential for selecting a suitable donor prior to transplantation. Although current HLA typing can be performed with relatively high accuracy, most methods do not provide any information on which HLA genes were inherited together from a single parent. This determination of genes located together on the same chromosome is called haplotyping. It is difficult to achieve using short NGS reads because of the long spans of DNA that occur between the genes.
>The GenDx assay, based on Dovetail® Micro-C proximity ligation technology, will be able to determine if a donor and recipient carry the same HLA haplotype. When they do, the chances of an extended match (beyond HLA genes) are much higher. This can potentially lead to a better transplantation outcome.

Wietse Mulder PhD, CEO of GenDx, commented: “Haplotyping of the crucial HLA genes is currently really challenging. The new strategy offered by the Dovetail Micro-C proximity ligation assay now unveils an outlook of better typing options for the HLA field. We believe that transplant patients will finally benefit from this technology ”.

About Proximity Ligation-Based Haplotype Phasing

Proximity ligation approaches have been well known for their ability to capture long-range genomic information. However, they have been unsuitable for genotyping due to significant sequence coverage gaps. Traditional approaches miss up to 20% of the human genome. Through re-engineering how the assay is performed, Dovetail Genomics has addressed this shortfall. Now, SNP phase information can be captured alongside primary genome sequence at coverage levels comparable to or exceeding shotgun libraries. Compatible with targeted enrichment using a hybrid capture panel designed against the 4-Mb HLA region, the technology has been demonstrated to fully capture and phase genetic variation across this entire HLA region.

State-of-art HLA typing analyses rely on comparison of SNP genotyping calls to allele frequency databases to call alleles. Due to the short-range nature of today’s NGS instruments, ambiguity in these calls may exist. Additionally, due to this limited information, it is not possible to resolve parental inheritance. Dovetail’s long-range information inherent to the datatype not only enables more accurate calling for the alleles typed today. It is also capable of fully resolving haplotypes for all genes in the HLA region.

About High-Resolution HLA Typing

The Human Leukocyte Antigen (HLA) system consists of a large family of highly variable genes and many allelic variants. These form the basis of the human immunological defense system. In stem cell transplantations, HLA matching of patient and donor is vital. Even small differences between HLA alleles may have serious effects on transplantation outcome. High-resolution genotyping is a technology which enables determination of even the smallest variations in HLA genes. Therefore, it is ideal for stem cell transplantation purposes.

Until recently, Sanger sequencing-based HLA typing was considered the gold standard for high-resolution typing. Today, Next-Generation Sequencing (NGS) has been adopted by the vast majority of HLA laboratories worldwide. It has become the new gold standard. This NGS approach offers higher resolution and is more amenable to high-throughput processing.

As one of the pioneering companies in the HLA field, GenDx started offering NGS strategies in 2013, consisting of NGSgo® reagents and the NGSengine® software package for various NGS platforms.
>NGSgo®-AmpX was CE marked in 2014, and the NGSgo full workflow compatible with Illumina MiSeq® received the CE mark in 2016. Since 2017, NGSgo & NGSengine are also registered as IVD at Health Canada.

Changes Under IVDR

GenDx has obtained the CE certificate under the new IVD Regulation (IVDR) for NGSgo® reagents and NGSengine® software (read more about this here).

Although the content of our kits remains the same under the IVDR, there are some important changes regarding:
√ Catalog numbers
√ Kit labels
√ Instructions for use

Changes in catalog numbers

NGSgo-AmpX v2 ● NGSgo-MX6-1 ● NGSengine
Because transitioning from IVDD to IVDR involves major administrative updates, catalog numbers have changed for several products*. Please take note of the following change in catalog numbers:

Although these catalog numbers have changed, the content of these products remains the same.

(*NGSgo-MX11-3 and NGSgo Library Full Kit are also CE marked under the IVDR. Catalog numbers for these products will remain the same, as these products were launched more recently and therefore complied with IVDR from the beginning).

When to start ordering the new catalog numbers?

NGSgo-AmpX v2 ● NGSgo-MX6-1 ● NGSengine
You can start ordering NGSgo-AmpX v2, NGSgo-MX6-1, and NGSengine under the new catalog numbers from June 15, 2022. To allow a transitioning period, ordering under the old catalog numbers remains possible until December 1, 2022. However, we would like to urge you to switch to the new numbers as soon as possible.

NGSgo-MX11-3 ● NGSgo Library Full Kit
We will start shipping NGSgo-MX11-3 and NGSgo Library Full Kit under the IVDR from June 15, 2022. As these catalog numbers do not change, this does not involve any ordering changes for you.

Changes in kit labels

New UDI code
Under the IVDR, product labels will contain a Unique Device Identifier (UDI). This is a barcode consisting of the following parts:
(01) product code (unique for each catalog number)
(10) lot number
(17) expiration date in YYMMDD format, where DD is 00 if day is not specified

You will find the UDI code on the kit labels for unambiguous identification of the kits in order to facilitate their traceability. For NGSengine, the UDI code will be displayed numerically on the splash screen of the software and will include the software version.

New label design

Labels have been slightly redesigned, including re-organization of symbols. New is a link to the location of the electronic version of the Instructions for Use: www.gendx.com/ifu.

Instructions for Use

New IFU versions

There are new versions of the Instructions for Use (IFU) for our IVDR products. The main changes in these versions include an updated intended purpose and additional product information. The laboratory protocols have not changed.
Next to English, these new versions of the IFUs will become available in various other European languages.

No printed IFU in kit

Under the IVDR, we are no longer including a printed version of the IFU in the kit. Instead, you can download the IFU from www.gendx.com/ifu.
If you do need an IFU in paper form, just send a request to support@gendx.com and we will ship a printed copy.

The first company in the field of transplant diagnostics complying with the new IVDR in Europe

PRESS RELEASE

We are very excited to share with you that we received the EU Quality Management Certificate (IVDR) by our notified body Tüv Süd for diagnostic use of our HLA product portfolio. This new IVDR (EU) 2017/746 sets increased standards of quality and safety for diagnostic use of medical devices to ensure the highest level of public health protection.

The IVD Regulation retains all existing IVD Directive requirements, and includes new stringent additional  conditions for in vitro diagnostic devices. Establishing increased quality management, continuous evaluation during the products life cycle and more technical documentation to prove effectiveness are included now. The GenDx HLA portfolio under IVDR contains NGSgo® reagents and NGSengine® software for high-resolution HLA typing. Being one of the first to get certified under the IVDR sets a bench mark for similar products in the field of HLA typing, especially for stand-alone software.

Given the complexity of capturing validation data and building extensive dossiers to obtain IVDR certification, only a few IVD companies have obtained this new certification. The majority of manufacturers is still in the process to implement and prove IVDR compliance for their products.

Therefore, the EU decided recently that, although the effective date of 26 May 2022 remains unchanged, under certain conditions, manufacturers will receive more time to transition to the IVDR. This also applies for GenDx’s chimerism monitoring products, currently CE self-marked under the IVDD.

Wietse Mulder PhD, CEO of GenDx, commented: ‘After a few years of extensive teamwork, we are proud to be the first global supplier in the field of transplant diagnostics, being able to offer a full HLA workflow portfolio under the new IVD Regulation. As a result we can continue to provide our customers with certified products, claiming increased safety and offer improved quality, that will finally benefit transplant patients”.

Benefits

• Hemato-oncology diagnostic assays
• Targeting leukemia molecular markers

Description

In collaboration with University Medical Center of Utrecht (UMCU), GenDx has added a new assay to its product portfolio which is tailored for detecting genetic markers in blood cancers. NGSgo ONCOdentify® identifies mutations within the JAK2, CALR and MPL genes, valuable for the prognosis and selecting treatment options for myeloproliferative neoplasm (MPN).  In the coming period, UMCU will validate these new assays in their routine laboratory work.

The MPN kit is the first of a series of assays to detect somatic mutations related to hematological malignancies like acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and chronic lymphocytic leukemia (CLL). The test can be used on Illumina sequencing platforms.

Next generation sequencing (NGS) offers advantages in accuracy, sensitivity, and speed with the potential to significantly impact the field of oncology. Because NGS can cope with a multiplexed approach of genes in a single assay, it reduces the number of multiple tests as an efficient and fast way to identify the causative mutation.

Wietse Mulder PhD, CEO of GenDx says: ‘Anchored on extensive knowledge of developing software and reagents for accurate HLA typing, we can now offer NGSgo ONCOdentify as a highly sensitive assay for detection of mutations in a tumor sample. We are convinced that this assay is a valuable contribution to improve tailor made treatment of blood cancers. ONCOdentify is now launched as Research Use Only (RUO), but we are in the process of validating it for In Vitro Diagnostic (IVD) device’.

Prof dr. Hidetoshi Inoko

★ 4th of January 1948 – † 3rd of January 2022

Recently the sad news reached us that Prof. Hidetoshi Inoko has passed away. Professor Inoko was a pioneer in unravelling the genetic complexity of the MHC region at a time that the current methods for genetic analysis were not available.
Later he was involved in all aspects of MHC, such as evolution, anthropology, diversity disease association and transplantation.
He also had major functions and important influence in the HLA society.
Prof Inoko was a great inspiration to both of us which we will cherish.

Wietse Mulder and Erik Rozemuller

Message from American Society for Histocompatibility and Immunogenetics: 

It’s with sadness that we inform you of the passing of Hidetoshi Inoko. The following tribute was written by Seiamak Bahram and John Trowsdale.

In this age it is easy to forget just how tortuous analysis of human immunogenetics used to be but in fact most of the fundamental discoveries about the MHC  genes were made before high throughput sequencing came onstream. Hidetoshi Inoko recognised the value of large-scale structural analysis of the MHC region, in man as well as other species, in the 1980’s and was a great contributor to the advancement of our field before he contributed to the first sequencing of the complex in 1999. From 1990 he was an early adopter of DNA typing for histocompatibility. The other approach he exploited for disease mapping on a genome scale was that of polymorphic microsatellites, which led to one of the very first Genome Wide Association Studies (GWAS) ever performed, that of rheumatoid arthritis using over 27000 microsatellites, a major tour de force at the time (2005).

From 1966 to 1976 Professor Inoko did his BSc and PhD (Science) degrees at Kyoto University, followed by eight years at Keio before moving to Tokai in 1984. He spent a year in Trowsdale’s laboratory in London at Cancer Research UK (then ICRF) in 1986-7 and qualified for a PhD in Medical Science in 1987. He became a Professor in 1992. His leadership qualities were recognised as he was elected Chairman of the Department of Molecular Life Science in Tokai University’s School of Medicine in 1993 and Vice-Dean in 2000, followed by Dean of the Graduate School in 2002 and then of the School of Medicine in 2006, when he was also director of the Institute of Medical Sciences. In 2021 Hide become Project Professor of the Center for iPS Cell Research and Application (CiRA) and Emeritus Professor of Tokai University in 2013. He co-led, in the past 10 years, with Seiamak Bahram, the only French-Japanese joint INSERM-JSPS laboratory, focused on histocompatibility.

Professor Inoko was a Councillor for the International HLA and Immunogenetics workshops and he played a major role in several of these successful large-scale events as well as in the Asia-Oceania Histocompatibility and Immunogenetics Workshops. He was also President of the Japanese Society for Histocompatibility and Immunogenetics. A committed educator, he was a visiting lecturer in several Japanese Institutes as well as abroad.

As a work colleague Hide was unique, a friend larger than life. He enjoyed the pleasures of international travel, of companionship as well as Scotch whiskey and red Burgundy. He was also an avid golf player. Many of us were recipients of his generous hospitality and kindness in hosting visitors in Japan where he was active 18 hours a day to make sure his guests experienced the best of Japanese culture. Hide worked and played extremely hard and was always cheerful and open-minded.

Seiamak Bahram and John Trowsdale

Genome Diagnostics B.V., also known as GenDx, is now launching NGStrack® and TRKengine®, its newest RUO (Research Use Only) marked reagents and software for chimerism monitoring by NGS (next-generation sequencing). This method can be used as an alternative for the current conventional STR (short tandem repeat) technique, with NGStrack being significantly more sensitive. NGStrack provides reliable chimerism data, at both high and low percentages.

NGStrack makes use of 32 so-called indel markers to distinguish between donor and recipient, based on inserted or deleted DNA fragments. Together the 32 indels cover 362 distinctive nucleotide positions across 18 chromosomes, including X/Y chromosomes. Only minimal amounts of DNA are required from the pre-sample, since it only needs to be tested during the initial step of determining informative markers. This prevents a potential run out of pre-sample DNA during the monitoring phase.

TRKengine software interprets the informativity of the markers and quantifies the chimerism percentage in post-samples. Its use as data management system allows for insightful chimerism monitoring and trending over time.

The NGStrack markers overlap with the existing GenDx qPCR kits for chimerism monitoring (KMRtype® and KMRtrack®), therefore it is possible to use both methods in parallel. NGStrack reagents and TRKengine software are compatible with Illumina sequencing platforms. As such, NGStrack can easily be included in our renowned NGSgo® workflow that has been successfully used in HLA labs for many years.

Dr. Wietse Mulder, CEO of GenDx, commented: “We are thrilled to offer these products to the market, enabling users to combine their routine NGS for HLA typing with chimerism monitoring. As of today, the field has the choice to replace conventional STR by a far more efficient and effective technique!”

Ready to start chimerism monitoring by NGS? Contact us for additional information, we will be happy to answer your questions!

NGSengine has been updated!

We have released the new version of our NGSengine software. Version 2.23.1 includes several new features and improvements, and the latest IMGT/HLA database 3.45.1.

HML exporter now available

To facilitate the digital reporting of HLA testing results and the collection of the raw probe, primer, and sequence data, the NMDP Bioinformatics group developed a software reporting format in 1998 but maintenance and extension became increasingly difficult due to the rigid format limitations. Therefore, the NMDP Bioinformatics group developed an XML-based reporting format to address the shortcomings of the previous format. The XML-based format is called Histoimmunogenetics Markup Language (HML) and is intended as a potentially general-purpose format for exchanging genetic typing data.

From the version 2.23.1 of NGSengine onwards, you will be able to export the typing results also in HML format. This has been a long-awaited feature as HML is the format of choice to upload data in the IHIW 18 workshop, to which GenDx is a sponsor and official partner. Now any user of NGSengine will be able to create a .hml file and contribute to the database maintained by the workshop promoting research, science, and exchange of valuable data.

Interested?

For more information regarding the HML format check the publication “Histoimmunogenetics Markup Language 1.0: Reporting next generation sequencing-based HLA and KIR genotyping” or directly contact us at marketing@gendx.com

Gerben Cramer is a 25-year-old student, currently enrolled in the master’s program ‘Public Sector Management’, and living in Leiden, The Netherlands.

In the summer of 2020, Gerben did something extraordinary: he donated his stem cells to an anonymous patient. We wanted to learn more about what it can be like to be a stem cell donor, and were happy to get in touch with Gerben. Enjoy reading!

When and why did you decide to register as a stem cell donor?
In January 2020, a good friend of mine sent a message in a group WhatsApp, sharing the story of a friend of his, who underwent a stem cell transplant as a treatment for leukemia. The road to receiving the transplant was a bumpy one, as the initial stem cell donor cancelled last minute. As a result, they had to consider finding an eligible donor within the family. The mother turned out to be the best fit, but given her age, it was a risky procedure. Fortunately, the transplant went well, and the patient survived. My friend concluded his story by saying: “Guys, please consider registering yourself as a stem cell donor, because my friend is luckily still alive, but there are still so many patients looking for a stem cell donor.” For me, this message was reason enough to sign up. I joined the registry the next day.

“For me, that message was reason enough to sign up. I joined the registry the next day.”

You were not registered for that long when you got the call?
Indeed! I was pretty surprised that Matchis reached out to me in March 2020. I did not expect to hear from them so quickly. They told me that it was indeed very unusual, but at that moment there was someone, somewhere in the world, in need of a stem cell transplant… and I was one of the five potential donors selected from the database. So then they examined my blood, and there was a more in-depth medical examination, questions about daily life, and my motivations. In the end, I turned out to be the best match for the patient.

What went through your mind when you heard that you were the best match?
Well, they asked me “Are you sure? Are you sure that you want to do this?”. I did not really understand the question, because I thought “Of course! There is a match, and I read that there’s only a 1 : 50.000 chance that you are selected as donor”. What was on top of mind for me, was that if I could help someone, I should do it. I found it amazing that I could do it, so I thought let’s go! Of course, I was also a bit nervous, but mostly I was grateful that I got to be the one to do this.

What do you think about the way you were informed about the procedure in general and the associated risks?
The guidance from Matchis was super good. They really took the time, checked in on how I was doing and how I felt about things, and were honest about the procedure and potential risks. Right from the start, a buddy from Matchis was assigned to me. I could really ask her anything, and she was there on the day of the transplant. That was really nice! They also arranged for a taxi to pick me up and get me back home. Everything is very well organized. Of course you are making an effort by being a donor, but still. It feels like a token of appreciation; they are happy that you are willing to do it.

Was there anything in particular that you were nervous about?
Yes, I was nervous about certain side effects. Personally, I was happy that my stem cells were taken from my blood, as there are less side effects associated with this method than donation via the bone marrow. But, in my opinion, the risk comes with the job, and I wanted to do the job.

Who decides whether stem cells are taken from blood or bone marrow?
You can indicate your preference, but eventually it is up to the patient’s doctor which method will be best for the patient. For example, for very small children, a stem cell transplant via the blood is more invasive than via the bone marrow. For older patients, the majority of transplant procedures are in the form of a blood transfusion.

What did the donation procedure look like? And how did you experience it?
72 hours before arriving at the hospital, you have to start with injecting a growth factor drug, to stimulate the body to make more stem cells. Someone from home health care (thuiszorg) came to my house to explain everything. The growth factors needed to be injected in my belly twice a day and fortunately my friends were willing to help me as it felt a little strange doing it myself at some point. Luckily, I did not experience too many unpleasant effects, whereas others do experience muscle and back pain. I was happy to start the donation relatively fit.

On donation day, 09.00AM, I arrived at the hospital. I took a seat, needles were injected in both arms, and then they started the transfusion; three rounds in total.

I found it a bit hard not to know the person for which I was doing this. It was someone, somewhere in the world, but that was all I knew; it remains anonymous. At some point during the day, they told me the patient’s gender and age. Also, I learned that the patient was on the heavier side, which meant that he needed more stem cells than the average person. So, it depends on how many stem cells are required for the patient whether the donation takes shorter or longer. For me, it took until 5.00PM.

My body had been working the whole day, and you basically ‘loose something’, so I was pretty exhausted.

“Only when I heard the good news about the patient doing well, it all felt more ‘real’ and personal. That’s when it really kicked in”

What was the donation like, on a more emotional level?
During the donation, I felt a little bit ‘distanced’ from the cause; you are laying there and at the end of the day, a courier comes along to pick up the stem cells. When I got back home, sitting on the couch, I really felt how tired I was. I could not tell too many people about the transplant, because of anonymity measures. Also, donor and patient can send each other a message, post donation, but that is all anonymous, so for all you know he might live as far away as Madagascar, or something. So, I just continued my life as normal, while I expected that what I just did would feel more special, but that was not really the case.

Only when I heard the good news about the patient doing well (6 months after the donation), it all felt more ‘real’ and personal. For me, it was at that exact moment that it ‘kicked in’. I do not mean this in an arrogant or selfish way, but I realized that the patient survived, because of MY stem cells. That felt so special.

“If I get the chance to make a difference again, I would do it. Without a doubt.”

Would you do it again? What if you turn out to be a good match for someone else in need?
Yes. Without a doubt! I have told my story to many others, hoping to inspire them to register as a stem cell donor as well, and if I get the chance to make a difference again, I would do it.

Let’s go!

Actually, after the donation, I was asked whether I would be willing to donate more stem cells or white blood cells for the patient, when needed. And of course I said ‘yes’. Typically, something like this would happen about 3 months after the donation. It didn’t happen eventually.

How long did the recovery process take for you?
Not that long, actually. Two days, max. But other than feeling tired, I did not experience any side effects. For the first 6 months after the donation, they make sure to check how you are doing on a monthly basis. After that, only every 6 months, and at a certain point it’s once a year. This way they can monitor whether there are any late side effects occurring after the donation. I definitely appreciate that they are checking in on me!

What would you like to say to people who are not sure if they want to become a potential stem cell donor? For example, people who are a bit scared of the procedure?
I can only speak from my own experience. I think it is most important to inform people, and I feel honored to be able to share my story and information on stem cell donation. Still, to be honest, sometimes I think: “Come on! There are patients, with leukemia for example, waiting for a stem cell donor. Just do it! You can potentially save a life!”… But even though I think everybody should sign up, everyone eventually has to make their own decision.

“The choice is yours, but actually you should just do it”

I really would like to say that the guidance from the Matchis foundation throughout the whole trajectory is absolutely superb. They are very professional and they really show their appreciation for the donors. I experienced that every nurse, every doctor, they all said “Thank you”, so I felt really valued. On the one hand, you are doing something really significant, and on the other hand, it is such a small effort… There is only a small chance that you are matched with a patient, but when you get the call, you can give a chance at life!

That is a beautiful conclusion. Thank you so much for sharing your story, Gerben!

Frans Paymans (61) is a former professional soccer player and a two-time cancer survivor.

He got diagnosed with non-Hodgkin’s mantle cell lymphoma in 2011. Back then, Frans was treated by means of his own stem cells. Unfortunately, the disease came back in 2016, and thanks to a match with someone from the stem cell donor registry, Frans was able to recover from the cancer. The battle was not over yet, due to graft-versus-host disease. This implies that donated cells (the graft) see the recipient’s cells (the host) as foreign and attack them; a reverse rejection so to say. Luckily, Frans fully recovered from this as well, and was able to go on. Nowadays, Frans is working as location manager on a school for special education. He is committed to keep raising awareness on the importance of stem cell donation, and associated topics.

“Eventually, it comes down to luck, and I have been extremely lucky!”

When were you diagnosed with cancer for the first time?
In 2010, I went to see a doctor after discovering a bump in my inguinal area. That turned out to be a swollen lymph node. In June 2011, I was diagnosed with non-Hodgkin’s mantle cell lymphoma, which is a relatively uncommon type of cancer that affects the lymphatic system and damaged about three-quarter of my bone marrow. By the end of July 2011, the treatment started at the Radboud University Medical Center in Nijmegen, The Netherlands. The first stem cell transplant was on January 24^th 2012, and those were my own stem cells.

Wait… what? Your own stem cells?
Yes, my own stem cells! It is called an ‘autologous’ stem cell transplant. The procedure is similar to when a donor goes through the donation process, involving growth factor drug injections to stimulate stem cell production. I first received chemotherapy, and that basically destroys your body, so I had just enough healthy stem cells that could be filtered out and collected by means of an apheresis machine. Eventually, your own stem cells are returned to the body through infusion. It cured me, but unfortunately the cancer came back completely in 2016.

What was the treatment like the second time around?
They went looking for a donor and, luckily, they found a very good match in the stem cell donor database; a young woman from the United States. Our blood group and HLA matched perfectly for the purpose of a stem cell transplant. Thanks to her donation, which was on October 10^th 2016, I received the stem cells on October 11^th 2016. I recently had my final check up with ‘my’ doctor. She and her team have been of unbelievable value. From now on, I only need to visit the outpatient department with longer intervals. They still need to monitor you, as there can potentially be residual effects from chemo, even after 10 years. Other than that, all is well.

How did you experience receiving stem cells from someone you do not even know?
I was pretty naïve at first, as I thought that getting stem cells was ‘as easy as buying a bread from the bakery’, but that turned out not to be the case… I was extremely lucky to match with a donor from the registry, and that donor is the reason I am sitting here, having this conversation with you, and the reason I can do everything I want to do.

And that’s why, a couple of years ago, when I was sitting on the top of a mountain in Norway, with my wife, I decided to share my story by publishing a book. A book about 60 years on this earth, and what it all meant to me and what it has brought me. And the ultimate goal was to donate part of the profits to Matchis and KWF Dutch Cancer Society.

The book is titled “It is a Competition” (Het is een Wedstrijd). What was it like to write that book? And, If I may say so, I get the feeling that to you, the battle has not yet ended…
It was a nice thing to do, but it was also very confronting, both regarding the period I was sick and the period prior to that. My main motivator to write this book was the thought of all those who do not live to tell about it.

And yes, on the one hand the battle is over, as last year I was able to leave quite some things behind me. All that’s left, is the possibility of residual effects from the chemo therapy that I had back in 2011. But, on the other hand, there is still a need to increase the chances for others to find their perfect match, that battle will never be over. I am committed to raise as much awareness about the topic as possible, and I really want to motivate people to register themselves as a stem cell donor at Matchis.

Looking back to the moment you just got the diagnosis. You told me that you did not know what you were up against at first. How did you cope with that? And what were your first experiences during treatment?
Well, my wife is a nurse and she pretty much knew what was coming, but initially, I had no idea what I was up against. After the diagnosis, driving back home in our car , there was an item on ‘Alpe D’HuZes’ on the radio. That was the first time I truly realized what that initiative was for, and that really hit me hard. When we got home, we first had a good cry. Then, the questions started coming: “What does this all mean? Am I going to survive this? Will I live to see my grandchildren?”. My wife and I met in 2010, and in June 2011 I got the diagnosis, so we had not been together for that long. We wrote down all our questions, and contacted my doctor, who was willing to discuss everything we wanted to know. What I really appreciated, is that she was transparent and straightforward.

At some point, after chemo started, I woke up looking at my pillow covered with plucks of hair that had fallen out. I realized at that moment that this was a first tangible result of the chemo. I had a couple of outpatient treatments, but at some point I was in the hospital for about 78 days, divided over 3 hospital admissions. Both the treatment and recovering from the treatment was, to put it mildly, not always the most pleasant experience. Basically, all that’s left is a body with a beating heart. You feel exhausted. You do not have any energy to do anything, not even to take a shower in the morning.

“Basically, after chemo, all that’s left is a body with a beating heart. You feel exhausted.”

Would you say that your athlete mentality benefited you throughout the whole trajectory?
Yes, I definitely think that my love for sports helped me back then, and that motivated me to get on the home trainer at least 2 and sometimes 3 times per day, for about 15-20 minutes. I did this to keep myself busy, but was also hoping it would contribute to my recovery. Still, eventually it comes down to luck, and I have been extremely lucky.

Actually, around the time I got my first treatment, in 2011, they started with research regarding the effects of working out prior to cancer treatment. I believe that nowadays, health insurances are covering costs for personal training for people who need to get treatment so they will start at a higher fitness baseline. So, that is a beautiful development, if you ask me.

What else helped you to get through the treatment and recovery?
My wife. She was there for me. You really need that ‘second person’ to be there during meetings with the doctor, as you are only able to process half of what they are telling you. The role of the partner is extremely important, and sometimes even underexposed. Imagine what they are going through: keeping their day to day life running, commute to and from the hospital, worrying about you and going to bed alone, scared that you might not be there anymore when they wake up the next day…  That is extremely hard and I think there should be more awareness about this as well.

Also, what I remember very vividly, is something that happened in 2012, when I was doing extremely unwell. My old soccer team, N.E.C. Nijmegen, played against my favorite soccer team, Feyenoord. There was a gigantic banner, put up by the crowd in the stadium, that said: “Frans, keep fighting” along with a huge painting of my face. It touched me deeply. I got so many messages after that. The original banner is completely weathered by now. To my surprise, the boys who made the original banner gifted me a small replica, on canvas, a short while ago. That was heartwarming.

I learned that it is possible to send an anonymous letter to the donor. Did you do that?
Not yet… it did cross our minds many times already, but it wasn’t the right time. In October 2021, it will be exactly 5 years ago that I got the stem cell transplant, so we are planning to send the letter then. A short while ago, during the “Stamweek”, I got the chance to read out loud part of the letter to my donor, live on radio station 3FM. That was very special.
The people from Matchis and the Radboud UMC stem cell consultants will be translating the final letter for me, and make sure there is no information in it that can be traced back to me. They will then send the letter to my donor.

Why did you decide to wait for the five year mark?
Things can still go wrong. And for me, it did. When I was finally cured from cancer, I got graft versus host disease, which made me very sick – it felt like I died a few times. Fortunately, after a lot of research, they were able to cure me from that. So, that also confirmed that waiting for that so-called ‘magical’ five year mark before contacting the donor, was a good decision.

“I did not have any control over my own body. I felt desperate and powerless.”

That must have been real hard, to get so sick after healing from cancer…
I did not have any control over my own body. It mainly affected my gut and later on also my skin.  I felt desperate and powerless. I was extremely dehydrated, and I had random blackouts that I did not even consciously experience. It was horrible. Fortunately, I fully recovered and can now enjoy the outdoors, biking and walking again.

To conclude, what would you like to say to people who are considering to become a stem cell donor, or who are still hesitating?
The beauty of this day and age, is that most of stem cell donations are taken via blood. In only a small proportion of donations, stem cells are taken from bone marrow. Most people can donate via blood, which involves growth factor drug injections, followed by harvesting by means of the apheresis machine. This procedure typically comes with mild, flu-like side effects that last only a couple of days. Then it is gone. So, if you are willing to pay that relatively small price, to really make a difference for a patient in need of a stem cell transplant, please… do not miss out on that opportunity! There are so many people who deserve it, just as I was lucky enough to receive stem cells from that young woman in the US. To all young men and women: let’s go, come on, please, join the registry!

£2.029 cheque handed to Beachon Cancer Charity

Thanks to the contributions of the participants of the #EFI2021 virtual Tulip Run and the multiplication from GenDx, EFI president Ann-Margaret Little and her colleague Helen McFarlane were able to hand over a cheque of £2.029 to the Beatson Cancer Charity in Glasgow. COVID restrictions caused a delay in the in-person handover, but happily, it could be realized now.

Grateful thanks to everyone who contributed!

Maisie McCormick, Community Fundraising Manager at Beatson Cancer Charity mentioned: “On behalf of everyone at Beatson Cancer Charity, thank you for your kind and generous donation of £2,096.79 raised through this year’s Tulip Run. What an incredible donation – it just goes to show how your generous clients and contacts used their initiative and got out to do their run wherever they were, despite not being with others. We are thrilled at having received such a fantastic donation. Please pass on our grateful thanks to everyone who contributed in some way. Thanks to your support we can continue to invest in services, staff, research, and education to provide a better future for those affected by cancer”. 

Thank you all for your support and looking forward to meeting you at the next Tulip Run event!

GenDx has registered NGSgo®-MX11-3 as CE-marked IVD

The product can now be used for accurate HLA typing of donors and patients in need of organ or stem cell transplantation. The approval of NGSgo-MX11-3 completes the series of our CE-marked IVD amplification products. This series includes a singleplex (NGSgo®-AmpX v2) and a six-gene multiplex (NGSgo®-MX6-1) strategy. They are used for HLA typing by Next-Generation Sequencing (NGS). All amplification products can be used in combination with the recently CE-marked IVD Library Full Kit. This kit is for indexing, library preparation, and cleanup.

NGSgo-MX11-3
NGSgo-MX11-3 consists of amplification primers for eleven HLA genes (HLA-A, -B, -C, -DRB1, -DQB1 and -DPB1, DRB3/4/5, DQA1, and DPA1). Its three-tube design results in low noise levels and well-balanced alleles. It provides similar high-quality data with the 11-loci multiplex compared to the singleplex strategy.

Dr. Wietse Mulder, CEO of GenDx, commented: “We are proud to now offer the NGSgo-MX11-3 multiplex amplification for diagnostic use. Furthermore, we are convinced this innovative product will accelerate the demand for high-quality multiplex data for stem cell transplantation”

Starting from NGSengine version 2.20, the software reports the Bw4/6 status of HLA-B alleles (based on the ALLAN tool*) in the overview, genotype ranking, TARR export, and the PDF report.

We are happy to announce that HistoTrac now accepts the tarr file as input and thus labs are able to transfer the Bw4/6 assignments directly into NGSengine.  In addition, making use of the conclusive typing feature is now compatible with the import as well as the transfer of NMDP codes, if there are ambiguous typings.

Interested?

Contact HistoTrac today to have your module updated so you can make use of this feature.

For those who have faced a deadly disease such as leukemia, it seems like life has been divided into ‘before’ and ‘after’. When you are on the waiting list for a stem cell transplant, you just have to wait and hope a suitable donor will be found. We got to interview leukemia survivor Tom Barendregt (22) about successfully battling this violent disease not once, not twice, but three times. Read more about Tom’s first-hand experience in receiving a stem cell transplantation and his understanding of how crucial it is to have strong spirit during such uncertain times.

Can you tell me a little bit about yourself. What is your life like and how did you get diagnosed with leukemia for the first time?
Before I got diagnosed with leukemia, I played ice hockey on a professional level. On the age of fourteen I already got my first professional contract in the first division of the Netherlands. When I was fifteen, I transferred to the Colorado Thunderbirds in Denver in the United States. I played here for one year, but due to compulsory education, I had to move back to the Netherlands to finish school. While finishing school I played in the Dutch first division again. From the moment I finished school I moved back to the US to play in the USHL, the highest league in the world for guys until the age of 21. Just before the start of the season I started to get weird symptoms like extreme tiredness, bruises on my body and pain in my lower back. I visited multiple doctors and tried different therapies, but nothing seemed to help. I decided to go to the hospital where they took a blood sample. They immediately diagnosed me with leukemia, a disease I had never heard about before. My suggestion was to give me some medication so that I could start the ice hockey season. But when they told me that the leukemia was in a very far stage and that one ice hockey puck to my body could be life threatening, I realized that it was very serious. Instead of starting the ice hockey season, I ended up in the hospital to start chemotherapy. The start of another type of top sport: fighting leukemia.

“I ended up in the hospital to start chemotherapy. The start of another type of top sport: fighting leukemia.”

So when you got diagnosed with leukemia, you were all alone in a foreign country?
Yes, that’s right. The only people that were around at that moment were my host family and my former girlfriend, who was about to start her study in Madison. Since the leukemia was already in a very far stage, it was too risky to fly me back to the Netherlands for treatment. One day after the diagnosis, I was hospitalized in the University Hospital in Madison and my father and the father of my former girlfriend travelled to the US to support me in the process.

Can you tell us something about what you have been going through from the moment you started treatment?
Before I started treatment, I was confronted with the message that the treatment would pose a high risk for infertility. I was 17 years old at that time, so I wasn’t thinking of having children at all. However, to be prepared for a potential wish for children in the future, I was sent into a room with a plastic jar and a playboy magazine. Then we started the induction phase, which is 30 days of chemotherapy. After one week I got a severe allergic reaction that nearly killed me. For the remaining 3-4 weeks they switched to intramuscular chemotherapy, which is given as injection into a muscle. I had many bone marrow punctures and lumbar punctures to see if there was cancer in my brain. Luckily there were no cancer cells in my brain, but they injected chemo there anyway for preventive reasons. After all, leukemia can hide anywhere.

“Leukemia can hide anywhere”

How long did it take until a suitable donor was found and you actually got a transplant?
There are multiple ways to fight leukemia, a stem cell transplantation is not always part of it. In my case, they decided on a treatment without a stem cell transplantation at first, so only chemotherapy and steroids. Four months after my diagnosis, they recognized that my leukemia was pretty aggressive and they therefore decided to change the method and continue with a stem cell transplantation. I consider myself lucky that I quickly matched with multiple donors in the database. When you are more racially mixed, it gets more complicated to find a donor and it often takes months or even years. Time you don’t have when you suffer from a life threatening disease like leukemia. Before you start with the stem cell transplantation, you receive treatment to destroy the cancer cells, your own bone marrow cells, and immune cells. So your body is quite destroyed. Then you get a transplant.

“I consider myself lucky that I quickly matched with multiple donors in the database”

How long did the recovery take place
From the moment you receive the stem cells, you are far from done. First of all you are monitored regularly to measure the effectiveness of the transplantation. In my case, I had pretty severe graft-versus-host symptoms, meaning that the donor T cells were attacking my healthy cells.
After approximately 9 days, they saw that it was starting to work. Exactly two weeks after I got my transplant I left the hospital. This was extremely fast, because normally you’re there for 6-8 weeks. After 3 months they did a bone marrow puncture to check how much of the bone marrow was now from the donor.
The whole transplantation and coping with its side effects took me an additional 7-9 months. And like I said, even when they don’t see the leukemia anymore, it can always come back.

And it did come back… twice.
How did the second and third treatment compare to what you had been through already? Did it start all over again, or was it different from the first time?
With my second diagnosis they suggested a new treatment method called CAR-T therapy. In CAR-T, T-cells are taken from your blood and modified in the lab by adding a man-made receptor. This receptor helps to identify the bad cells.
The third treatment was comparable with my first since I had a stem cell transplantation. In principle these treatments were pretty much the same, the main difference was that with the third treatment they used immunotherapy instead of chemotherapy. Immunotherapy is a relatively new cancer treatment that boosts the immune response in the body as well as teach the immune system how to identify and destroy cancer. The reason why they tried this different method is because there were mutated leukemic cells hiding in my testicle. Since these mutated cells had another genetic code (CD22), it was not recognized by the CD19 CAR-T cells.
An interesting fact is that both with the second and third diagnosis, the leukemic cells were hiding in my testicles. More and more research shows that this is a very common place for the cells to hide in a men’s body, therefore radiation on the testicles is included in the standard treatment procedure in the US. Upon my last treatment, I had twelve radiation sessions on my testicles just before the transplantation. This was to minimize the chance that leukemic cells were able to hide there again.

Your third fight against leukemia was during the first months of COVID-19. Since your immune system was (about to be) killed by chemo, were you afraid that COVID-19 could get to you? |
When you are in the process of radiation and stem cell transplantation, a cold is already dangerous to you. So you are very careful, whether there is a pandemic or not. At that time, the lockdown was in effect and the only main difference I experienced was that the visitor schedule in the hospital was heavily regulated. I therefore took a flat screen TV with PlayStation and some dumbbells with me to the hospital to keep myself busy. After the transplantation it was easier to go outside, since it was very quiet on the streets and everyone kept their distance.
Since acute leukemia is life-threatening, unlike other less life-threatening diseases, they didn’t postpone my treatment and transplantation. Because of the pandemic, it did take a bit longer to transport the stem cells from my donor in Germany to the Netherlands.

You have beaten leukemia three times now. After so many times, how do you stay positive?
I think the most important thing is that I put everything in perspective. When I think of everything I have been through and the fact that I nearly faced death, every day that I am not ill is a good day. Nowadays, I only put effort in the things I like to do and invest in the persons I like to have around me. I enjoy life to the fullest. By eating a healthy diet and exercising regularly, I make sure my body is ready for any battle to come.

“I focused on the things I could control, and let go of what I couldn’t”

What would you say to someone who is  at the start of the fight against leukemia or another type of cancer?
It is hard to accept that you don’t have control over the way your body is dealing with the disease and whether your will survive or not. What helped me a lot was to focus on the things I could control, and let go of what I couldn’t control. For me this meant that good nutrition and exercise was more important than ever and I focused on gaining knowledge about the disease so that I could join the conversation and be involved in the decision-making process. Being in control over the things you can control also gives you peace. In case you would die, you would at least know that you did everything within your power.
Another thing that I would recommend is to focus on the people that you really care about. When you are diagnosed with leukemia or any other life-threatening disease, you get a lot of attention most of the time. Instead of investing in all these people, focus on the ones you rely on and care about the most.
It might also help to get in touch with fellow sufferers since they truly understand what you are going through.

Last question: were you able to play ice hockey on a professional level again?
The thing is that you have a higher chance on playing ice hockey on a professional level when you perform well in a junior hockey league between the age of 18-21. I was treated for leukemia at that time, therefore I have a slighter chance to get a contract in the US. Playing ice hockey in the first division of the Netherlands might be a possibility, however this is not the level I used to play so then it would be more like a hobby.
Therefore, I am focusing on other things at the moment. I get a lot of energy from motivational speaking and being an entrepreneur, working on healthy food products in cooperation with an American company. I just enjoy life to the fullest and focus on the things that make me happy!

Thank you Tom, for the inspirational story! It is really admirable how positive you are. We wish you all the best for the future!

Samenwerking GenDx en Universiteitsmuseum Utrecht

Het Universiteitsmuseum Utrecht (UMU) vormt sinds jaar en dag dé plek waar samenleving
en wetenschap elkaar ontmoeten. En met succes: de bezoekcijfers zijn de afgelopen jaren
flink gestegen, van 20.000 in 1996 naar 75.000 in 2019. Daar is het museumgebouw niet op
berekend. Na een grondige verbouwing is er bij heropening voldoende ruimte voor 100.000
bezoekers per jaar. Het UMU ontwikkelt zich van een wetenschapsmuseum tot een echt
onderzoeksmuseum. Volgens het principe van onderzoekend leren nemen we onze
bezoekers actief mee in het proces van wetenschap en laten ze deelnemen aan echt
onderzoek. Dankzij de steun van de Universiteit Utrecht kunnen we het museumgebouw
ingrijpend aanpassen.

Het herinrichten van het museum en het ontwikkelen van nieuwe presentaties doen we in
samenwerking met partners die het belang van onderzoek en wetenschapswijsheid
onderschrijven. De komende jaren zal GenDx, specialist in DNA-diagnostiek voor het
genetisch matchen van transplantatiepatiënten met donoren, een belangrijke financiële
bijdrage leveren aan deze herinrichting.

Wietse Mulder, CEO van GenDx: “de samenwerking met het UMU past ons goed. Wij weten
wat het betekent om als donor het verschil te maken. Het is daarom onze missie om de
kwaliteit van leven van transplantatiepatiënten wereldwijd te verbeteren. Dat vraagt veel
onderzoek. We vinden het essentieel dat het belang van onderzoek en wetenschap zichtbaar
is voor een breed publiek. Het UMU laat dat op innemende manier zien”.

“We zijn erg blij met de bijdrage van GenDx. Het brengt ons weer een stap dichterbij de
realisatie van onze droom”, aldus Paul Voogt, directeur van het UMU.

EFI 2021 will take place fully virtually from Wednesday, April 21 to Friday, April 23 and we are proud to be one of the Gold Sponsors.

UTRECHT – Van 2 maart tot 22 maart heeft GenDx, een bedrijf in de moleculaire transplantatiediagnostiek, haar medewerkers uitgedaagd om in beweging te komen voor het Prinses Máxima Centrum en Stichting Leergeld Utrecht. Ruim voor de deadline was het maximaal te behalen bedrag van €5.050 al verzameld door circa 40 sportieve medewerkers. Op woensdag 31 maart jl. zijn de cheques van €2.525,-  per doel overhandigd.

De doelstelling van GenDx Charity Challenge is bijdragen aan de fysieke en mentale gezondheid van medewerkers van GenDx in een periode waar – gedeeltelijk – thuiswerken, sluiting van sportscholen en -verenigingen, en minder sociale contacten het leven beïnvloeden. Deze activiteit sluit perfect aan bij de waarde van GenDx om te delen, hetgeen we ook binnen het werkveld van transplantatie diagnostiek van groot belang achten.

GenDx, gelegen op het Utrecht Science Park, is als spin-off van UMC Utrecht een van origine Utrechtse onderneming.  Wij zijn trots op ‘onze afkomst’ en steunen daarom verschillende lokale organisaties, waaronder Stadsschouwburg Utrecht, sportverenigingen Histos, Triton, Orca en SPIN en zeer recent het Universiteitsmuseum Utrecht. Voorafgaand aan de start van GenDx Charity Challenge kregen onze medewerkers de kans om een goed doel te kiezen uit een lijst van zowel lokale als internationale initiatieven, met als resultaat de keuze voor het Prinses Máxima Centrum en Stichting Leergeld Utrecht.

Beide organisaties willen het gedoneerde bedrag gebruiken om kinderen te laten bewegen. Stichting Leergeld Utrecht zet het bedrag in voor een specifiek project om kinderen uit lage-inkomens gezinnen te ondersteunen met hun contributie voor sportclubs. Binnen het Prinses Máxima Centrum wordt de donatie gebruikt voor de afdeling Quality of Life. Hieronder valt ook het Maximaal Bewegen project, dit programma richt zich op een sneller en beter herstel van kinderen met kanker door voldoende beweging en een verlaging van de stress bij kinderen en ouders tijdens het behandelproces door afleiding en sporten.

Have you heard about PIRCHE?

Register now for our webinar on February 16:

PIRCHE Epitope Matching in Kidney Transplantation: A Case Study

PIRCHE® is a new technology for estimating the risk of immune responses after transplantation. It is the first HLA matching algorithm taking into account the indirect pathway of allo-recognition. PIRCHE currently has more than 650 users in 57 countries.

The input of the algorithm is the HLA genotype of a sample. The output of this algorithm is a score (number), to be considered when searching for a donor.

With NGSengine version 2.16 or higher, you can have access to the PIRCHE export feature. GenDx customers can also receive full access to the full range of PIRCHE epitope matching modules through the PIRCHE web platform. You only need to register selecting GenDx as preferred partner.

For more details, visit www.pirche.com

GenDx is a proud sponsor of the AFDN (Allele Frequency Net Database) website. AFND is a very useful tool for researchers as they can search population frequencies of several immune genes such as Human Leukocyte Antigens (HLA), Killer-cell Immunoglobulin-like Receptors (KIR), Major histocompatibility complex class I chain-related (MIC) genes, and a number of cytokine gene polymorphisms. It contains information at allele, haplotype and genotype level depending on the polymorphism. Users can now find on the website data from more than 2000 populations on 7 million individuals.

AFND is currently maintained by researchers at Royal Liverpool University Hospital and the University of Liverpool, in collaboration with other international scientific groups.

We proudly announce that earlier this year we have appointed Professor Seiamak Bahram as scientific advisor to our company. Professor Bahram has an extensive knowledge of the Major Histocompatibility Complex (MHC) and in particular the MHC Class I chain-related molecules A (MICA) and B (MICB). His scientific advice will provide valuable input to the company regarding relevant immunological targets and the use of diagnostic assays in a hospital setting.

The NGSgo® Workflow has now been visualized! We have recorded the protocol steps of the NGSgo® Workflow in 9 separate videos.. In these videos, our colleagues Jannetje Kooij B.ASc, Remco Malestein B.ASc and Robert Welleweerd B.ASc show you how to execute each step of the workflow. The videos can be used as an addition, not as a replacement, to the available Instructions for Use.

All videos are now available on our website: www.gendx.com/gendx_education/instructional-videos-ngsgoworkflow/

The multiplex you have been waiting for!

Amplification primers for eleven loci are multiplexed in three tubes. The three-tube design results in lower noise levels, better-balanced alleles, and higher quality compared to a one-tube approach. This means more reliable typing results.

From DNA to results in only 1,5 days!

Start your amplification on day 1 and have your typing report on day 2 before noon. You can run 16 samples on an Illumina micro flow cell.

2020 is a milestone year for both GenDx and student rowing club Orca. While GenDx celebrates its 15^th anniversary this year, Orca will reach its 50^th anniversary in October, a huge accomplishment for both.

GenDx CEO Wietse Mulder has been a member of Orca from 1983 to 1996, participating in several rowing races with his Orca team ‘Dé clubacht’. Several other Orca teams were competing at the same time, and there was always some rivalry over which team would get to use the best 8⁺ boat. As Wietse and his team did not always win the boat struggle, they jokingly said that one day they would buy their own boat.

In the milestone year 2020, Wietse decided to buy the boat for Orca, and on Saturday, August 22, Wietse baptized the brand new 8⁺ Filippi boat in the presence of current Orca members, as well as his former team members. During the ceremony, Wietse elaborated on his reasoning to support the club and referred to two of his main entrepreneurial strategy principles: ‘Dare to share’ and ’Do not always expect a return of investment’.

After the ceremony, pictures were taken of the boat and the (former) Orca members, taking the COVID-19 restrictions into account. The pictures show the beautiful boat with special GenDx graphics, designed by Leon Hulst from WAT Ontwerpers.

Last week, Wietse Mulder PhD (CEO, GenDx) and Joost Kook (Deputy Director, Stadsschouwburg Utrecht) have signed a new contract for three years to confirm mutual engagement and strengthen their cooperation. Three years ago, GenDx became partner of the Stadsschouwburg Foundation. In the new contract GenDx becomes a founder.

Please find the full press release in Dutch below:

GenDx en Stadsschouwburg verstevigen samenwerking

Afgelopen week ondertekenden Wietse Mulder (PhD, CEO van GenDx) en Joost Kok (adjunct-directeur Stadsschouwburg Utrecht) een nieuwe overeenkomst voor drie jaar om de wederzijdse betrokkenheid te bevestigen en de samenwerking te verstevigen. Drie jaar geleden trad GenDx toe als partner van de Stadsschouwburg Foundation. In het nieuwe contract wordt GenDx founder.
De Stadsschouwburg Foundation is een alliantie van Utrechtse organisaties en bedrijven die de schouwburg in staat stellen jaarlijks een aantal exclusieve (en kostbare) producties in het programma op te nemen. Als waardering voor hun steun biedt de schouwburg deelnemers aan de foundation bijzondere faciliteiten zoals ontvangsten van relaties, ontmoetingen tussen founders en diverse vormen van exposure. Andere Founders zijn Douwe Egberts, Rabobank Utrecht e.o. en de Provincie Utrecht.

Wietse Mulder (PhD, CEO van GenDx):
“Drie jaar geleden zijn we partner geworden van de Stadsschouwburg, met het volgende statement: ‘Wij weten wat het betekent om als donor het verschil te maken. Daarom is GenDx partner van Stadschouwburg Utrecht.’
GenDx is een Utrechtse Life Science onderneming en gevestigd op het Utrecht Science Park. In een tijd waarin nagenoeg geen voorstellingen kunnen worden gegeven bij de Stadsschouwburg, willen wij onze betrokkenheid versterken door founder te worden.
De relatie met de stadsschouwburg ligt ons na aan het hart en wordt door onze medewerkers zeer gewaardeerd. Zij kijken er naar uit om weer een voorstelling van eigen keuze bij te kunnen wonen. Daarnaast zijn we een tevreden bezoeker van restaurant Zindering, waar we regelmatig met onze gasten naar toe gaan.”

Joost Kok (adjunct-directeur Stadsschouwburg Utrecht):
“De Stadsschouwburg Foundation is een fijne plek waar veel Utrechtse bedrijven zich thuis voelen. De founders en partners steunen al jaren de activiteiten van Stadsschouwburg Utrecht. Zeker in deze tijd is deze steun hard nodig. We investeren veel in relatiebeheer waarbij het persoonlijke contact voorop staat. Dat dit werkt zien we aan een trouwe partner als GenDx, die nu besloten heeft om founder te worden. Het is hartverwarmend om te zien dat Gendx zoveel vertrouwen in ons uitspreekt, voor nu en in de toekomst.”

We are happy to announce that GenDx has registered NGSgo®-AmpX v2 and NGSgo®-MX6-1 as CE-marked IVD.

The NGSgo®-AmpX v2 and NGSgo®-MX6-1 primer kits are intended for the amplification of both HLA alleles present in a sample for downstream sequencing applications. They are intended for in vitro diagnostic use by professional users in diagnostic laboratories, such as laboratory technicians and physicians, trained in HLA-typing and DNA sequencing.

Customers that are interested in implementing these products to their workflow and wonder whether they could benefit from this registration, can receive more information by contacting their local GenDx distributor or by contacting GenDx directly.

Genome Diagnostics B.V. (“GenDx”) announced today that they have entered a collaboration with the Berlin-based company PIRCHE AG and have released a new version of their software NGSengine®. NGSengine, globally considered to be the ultimate Human Leukocyte Antigen (HLA) typing software for multiple NGS platforms, can now export HLA typing results of an individual sample directly to the PIRCHE matching services website. This will facilitate laboratories to predict indirectly recognizable HLA epitopes for either hematopoietic stem cells or solid organs.

About the PIRCHE algorithm
HLA mismatches between donors and recipients may lead to alloreactivity after transplantation. With the identification of numerous new HLA alleles, the risk of alloreactive responses towards HLA mismatches after transplantation has become more challenging to predict. The PIRCHE (Predicted Indirectly ReCognizable HLA Epitopes) algorithm has been developed to estimate the risk associated to alloreactive T-cell responses. The PIRCHE algorithm addresses the indirect recognition of HLA mismatches. It aims to improve transplant outcome by reducing Graft-versus-Host Disease and by enhancing Graf-versus-Leukemia effects after hematopoietic stem cell transplantation and cord blood transplantation. In the field of organ transplantation, the algorithm allows estimating the incidence of developing donor-specific antibodies against the transplant, which is considered the major risk of graft failure.

About High-Resolution HLA Typing
The HLA system consists of a large family of highly variable genes and allelic variants which form the basis of the human immunological defense system. In stem cell transplantation, matching patient and donor is vital as small differences between HLA alleles may have serious effects on the outcome of transplantation. High-resolution typing is a technology which enables determination of variations in nucleotides, making it ideal for stem cell transplantation purposes.
GenDx offers the NGSgo® reagent line and the NGSengine software package for NGS-based HLA typing.
