Abstract:
Objective:The aim of this study is to investigate the relationship between fat mass and obesity associated ( FTO) gene polymorphism and the risk of gestational diabetes mellitus (GDM), and provide clues and basis for the study of GDM mechanism. Methods:The case group of GDM pregnant women who delivered at the First Affiliated Hospital of Shanxi Medical University from March 1, 2012 to July 30, 2014 were selected, and matched the control group among non-GDM pregnant women by age, gestational age and residential address, and 324 cases and 318 controls were finally included. DNA was extracted and genotyped, and min P test and unconditional logistic regression model were used to estimate the relationship between FTO gene polymorphism and GDM. Results:At gene level, we did not find the association between FTO and the risk of GDM ( P>0.05). After adjusted for family history of diabetes, pre-pregnancy body mass index and multiple comparisons using false discovery rate method, unconditional logistic regression analysis showed that pregnant women who carried the rs11075995 TT genotype ( OR=0.59, 95 %CI: 0.35-0.89), rs3826169 GG genotype ( OR=0.59, 95 %CI: 0.35-0.88), and rs74245270 GA genotype ( OR=0.69, 95 %CI: 0.49-0.98), GA or AA genotype( OR=0.70, 95 %CI: 0.50-0.97) had reduced risk of GDM. However, pregnant women who carried the rs74018601 GA genotype ( OR=1.51, 95 %CI: 1.07-2.12), GA or AA genotype ( OR=1.46, 95 %CI: 1.06-2.02), rs7205009 AA genotype ( OR=1.83, 95 %CI: 1.18-2.86), GA or AA genotype ( OR=1.53, 95 %CI: 1.08-2.19), and rs9888758 AG genotype ( OR=1.43, 95 %CI: 1.02-2.00) had elevated risk of GDM. Conclusion:The polymorphisms of FTO gene rs11075995,rs3826169, rs74245270, rs74018601, rs7205009 and rs9888758 were associated with the risk of GDM.
