| Outline of Final Research Achievements |
Gestational diabetes mellitus (GDM) is regarded as one of the multifactorial disorders because its pathophysiology is similar to type 2 diabetes (T2DM) in metabolism. To date, GDM risk genes in Japanese women have not been analyzed. The aim of this study is to identify GDM candidate genes in Japanese pregnant women using T2DM risk gene variants. In this study, T2DM risk variants (45 single nucleotide polymorphisms [SNPs] from 36 genes) identified in previous studies were genotyped in a cohort of 171 Japanese women with GDM (n=171) and normal glucose tolerance (n=128). Of 45 SNPs, three genetic variants (insulin sensitivity: 1 gene, insulin secretion: 2 genes) were nominally associated with the risk of GDM. The combined analysis demonstrated that women with five or more risk alleles had an increased risk of GDM. Our data suggest several risk variants of T2DM had cumulative effects on the development of GDM in Japanese women.
