Jan Mohr

Jan Gunnar Faye Mohr, (10 January 1921 - 17 March 2009) was a Norwegian-Danish physician and geneticist, known for his discovery of the first cases of autosomal genetic linkage in man, between the Lutheran blood groups and the ABH-secretor system, and between these and the hereditary disease myotonic dystrophy. Besides being first steps in mapping the human genome, the findings illustrated the medical potential of linkage analysis in prenatal genetic diagnosis. Mohr is eponymously known by the syndrome Mohr-Tranebjærg, a progressive deafness with X-linked mode of inheritance, which was first described by Jan Mohr, and then more comprehensively by Tranebjærg et al. The 'Mohr syndrome', or oral-facial-digital syndrome type II, is named after Otto Lous Mohr, uncle of Jan Mohr.
