摘要: 目的 探讨has-miR-27a基因 rs895819位点和has-miR-124a 基因 rs531564位点单核苷酸多态性(SNP)与妊娠期糖尿病(GDM)发病的相关性。方法 共纳入1 719例孕妇,其中GDM 839例;糖耐量正常和50g葡萄糖负荷试验阴性者880例,作为对照组。采用TaqMan探针法检测两组孕妇SNP位点基因型,比较两组孕妇各SNP位点等位基因和基因型频率差异,以及不同基因型间临床生化指标的差异。结果1)rs895819位点CC、CT和TT基因型频率在GDM组分别为3.1%、39.3%和57.6%,对照组分别为7.1%、37.6%和55.3%,CC基因型频率显著低于对照组(P<0.05);隐性模型(CC vs CT+TT)中两组差异仍具有显著性[P=0.001; OR 0.435(0.270, 0.702)];GDM组C等位基因频率(22.8%)低于对照组(25.9%)(P<0.05)。 2)rs895819 CC基因型孕妇空腹血糖低于CT+TT基因型孕妇(P<0.05)。结论 has-miR-27a 基因rs895819位点与GDM相关,C等位基因降低GDM的发病风险。

Abstract: Objective To explore whether single nucleotide polymorphism (SNP) of has-miR-27a gene rs895819 and has-miR-124a gene rs531564 were associated with development of gestational diabetes mellitus (GDM). Methods A total of 1719 pregnant women including 840 with GDM and 880 controls with normal glucose tolerance (NGT) and negative result of 50g glucose challenge test [GCT(-)] were recruited. SNP were genotyped using TaqMan allelic discrimination assays. The genotype and allele distributions of each SNP between GDM and control groups and the biochemical data among different genotypes were analyzed. Results 1) The CC, CT and TT genotype frequencies of SNP rs895819 differed significantly between GDM group and control group (3.1%、39.3%、57.6% and 7.1%、37.6%、55.3%) (P<0.05), and the effect remained in a recessive model(CC vs CT+TT)[P=0.001; OR 0.435(0.270, 0.702)]. Moreover, the allelic frequencies of C was significantly lower in GDM group than in controls (P<0.05). 2) The levels of fasting plasma glucose in pregnant with rs895819 CC genotype were significantly lower than those with CG+GG genotype. Conclusions The C allele of rs895819 SNP in has-miR-27a gene reduced the risk of GDM.
