Abstract excerpt
The positional cloning of multifactorial disease genes is a major challenge in human genetics. We have therefore empirically tested the utility of the available polymorphic microsatellite map to locate the already identified type 1 diabetes locus IDDM1 (sibling risk/population prevalence ratio lambda(s)= 2.7) within a 14 Mb region of chromosome 6p21 linked to disease. In a two-stage approach to fine mapping,...
