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.
