DIEGG and DSGD. Danish IDDM Epidemiology and Genetics Group and The Danish Study Group of Diabetes in Childhood. PG - 67-70 AB - Recent genome screening studies have identified novel regions of possible interest for susceptibility to type 1 diabetes. One of these is a 30-35 cM region mapping to 16q22-q24 (D16S515-D16S520), where also the gene encoding NAD(P)H: quinone oxidoreductase (NQO1) maps. Data has suggested association of a polymorphism (P187S) in the NQO1 gene and type 1 diabetes. NQO1 is involved in protection against oxidative stress, which is likely to be involved in beta-cell destruction. By use of the transmission disequilibrium test (TDT), we analyzed the P187S polymorphism for association to type 1 diabetes in a population-based sample of 247 Danish nuclear type 1 diabetic families. Random transmission patterns were observed to all affected offspring (p(tdt) = 0.82), to index cases (P(tdt) = 0.77), as well as to unaffected offspring (P(tdt) = 0.93). Hence, the NQO1 polymorphism is not likely to be an etiological mutation underlying the reported linkage of the 16q22-q24 region.
