TCF7L2和KCNQ1基因多态性与2型糖尿病易感性的Meta分析

目的对TCF7L2,KCNQ1基因多态性与2型糖尿病(T2DM)相关性的研究进行Meta分析。方法通过检索PubMed和CNKI数据库中有关TCF7L2,KCNQ1基因多态性与T2DM易感性关联研究的文献,用漏斗图检验入选文献的偏倚,根据异质性检验结果采用固定效应模型或随机效应模型进行Meta分析,此过程均在软件包Launch Stata11.0上完成。结果该研究共纳入20篇文献(:1)KCNQ1基因rs2237892位点与T2DM发病风险相关性的研究共纳入7篇,得到7764例T2DM患者和8937例对照,Meta分析结果显示,rs2237892位点C等位基因能够增加T2DM的发病风险(OR=1.300,95%CI:1.234～1.366);CC/TC基因型是T2DM的危险基因型(OR=1.453,95%CI:1.279～1.651)。(2)TCF7L2基因rs7903146位点与T2DM发病风险相关性研究12篇,共得到11443例2型糖尿病患者和11003例对照,Meta分析结果显示,rs7903146位点T等位基因能够增加T2DM的发病风险(OR=1.379,95%CI:1.261～1.508),TT/TC基因型是T2DM的危险基因型(OR=1.469,95%CI:1.333～1.620)。(3)TCF7L2基因rs12255372位点与T2DM发病风险相关性的研究12篇,共得到12173例T2DM患者和10869例对照;Meta分析结果显示,rs12255372位点T等位基因能够增加T2DM的发病风险(OR=1.381,95%CI:1.275～1.495),TT/TG基因型是T2DM的危险基因型(OR=1.463,95%CI:1.337～1.602)。结论 TCF7L2基因rs7903146位点TT/TC基因型和rs12255372位点TT/TG基因型,以及KCNQ1基因rs2237892位点CC/TC基因型均能够增加T2DM的发病风险。

A Meta-analysis on the Association between TCF7L2/KCNQ1 Gene Polymorphism and Type 2 Diabetes

Objective To explore the association between the TCF7L2/KCNQ1 gene polymorphism and the occurrence of type 2 diabetes. Methods Literature-based searching was conducted to collect data (from PubMed, CNKI, etc). Funnel map was used to appraise publication bias, and the fixed-effects and random-effects meta-analysis were performed to pool the odds ratio (OR), which was selected according to the result of study-between heterogeneity test. All analyses were conducted in Stata software, version 11.0. Results This...
