摘要 目的探讨研究在汉族人群中转录因子7类似物2(TCF7L2)基因多态性与糖尿病易感性的关系。方法以70例2型糖尿病患者和70例正常健康志愿者为受试对象,均为汉族人,分别记为疾病组和健康组。对两组TCF7L2基因的rs290487和rs10749127位点的多态性进行检测,并对比基因型分布和等位基因频率差异,确定等位基因频率与2型糖尿病易感性的相关系数。结果两组TCF7L2基因的rs290487和rs10749127位点基因型分布对比差异均有统计学意义(P<0.05),且疾病组rs290487位点的C等位基因频率和rs10749127位点的C等位基因频率均明显高于健康组(P<0.05);在汉族人群中TCF7L2基因的rs290487和rs10749127位点的C等位基因频率均与2型糖尿病的发生风险有正向相关性(r=0.527、0.406,P<0.05)。结论在汉族人群中,TCF7L2基因的rs290487和rs10749127位点基因型分布和等位基因频率均与2型糖尿病的发生有紧密关系,且2个位点C等位基因频率越高,该病的发生风险也越高。
