Association of Polymorphisms in <i>PPARPGC1A,ACE</i>, and <i>DRD2 G</i>enes with Gestational Diabetes Mellitus

The aim of our research was to study the distribution of polymorphic variants of the DRD2/ANKK1 TaqIA (rs1800497 SNP), PPARGC1A rs8192678 SNP, and ACE I/D in gestational diabetes mellitus (GDM). Methods and Results: The study included 383 pregnant women (gestational age of 37.0-41.0 weeks) with GDM and 68 pregnant women without disturbed carbohydrate metabolism. This was a prospective case-control study. All patients were divided into 3 groups. Group 1 included 211 pregnant women with GDM who received diet therapy only; Group 2 included 172 pregnant women with GDM who received insulin therapy; Group 3 included 68 pregnant women without metabolic disorders. For the DRD2/ANKK1 TaqIA (rs1800497 SNP) (A1/A2; T/C), we found that the TT homozygous genotype and T allele prevailed in Groups with GDM compared with Group without metabolic disorders. Conclusion : A study of the DRD2/ANKK1 TaqIA (rs1800497 SNP), PPARGC1A rs8192678 SNP, and ACE I/D revealed statistically significant increased risks for GDM in carriers of the TT genotype and T allele of the DRD2/ANKK1 TaqIA (rs1800497 SNP)
