John Trowsdale is an Emeritus Professor, specialist in Immunogenetics, in the Department of Pathology, University of Cambridge UK. In the early 1980’s he was one of the first to clone HLA genes and to complete sequencing of the entire HLA region. In collaboration with Stephan Beck at the Sanger Centre he provided sequenced common HLA haplotypes, which were used as ‘gold-standard’ references. John’s interest in GenDx is in further development of rapid genetic analysis of highly variable genes such as HLA and KIR in human disease, such as infection, autoimmunity, cancer and pregnancy disorders. The link with GenDx is of mutual benefit in driving forward the use of next generation sequencing techniques to achieve rapid and accurate immunogenetic analysis. John visits GenDx to discuss how development of novel techniques at GenDx benefits the research and health care communities.
