Linkage of the gene for Wolfram syndrome to markers on the short arm of chromosome 4.
Wolfram syndrome is an autosomal recessive disorder defined by the occurrence of diabetes mellitus and progressive bilateral optic atrophy. Wolfram syndrome homozygotes develop widespread nervous system abnormalities; in particular, they exhibit severe behavioural difficulties that often lead to suicide attempts or psychiatric hospitalizations. The Wolfram syndrome gene also predisposes heterozygous carriers to psychiatric disorders, and may contribute significantly to the overall burden of psychiatric illness. Based on a linkage analysis of 11 families segregating for this syndrome using microsatellite repeat polymorphisms throughout the human genome, we found the Wolfram syndrome gene to be linked to markers on the short arm of human chromosome 4, with Zmax = 6.46 at theta = 0.02 for marker D4S431.[1]References
