摘要 目的:探讨黑龙江省东部地区汉族人群中转录因子7类似物2(TCF7L2)基因rs12255372-G/T和rs7903146-C/T单核苷酸多态性(SNP)与2型糖尿病(T2DM)及胰岛素抵抗(IR)的相关性。方法:选取黑龙江省东部地区汉族人群T2DM患者180例(T2DM组)及健康体检者150例(对照组),提取其血液样本DNA,PCR扩增目的基因后应用直接测序法对两组rs12255372、rs7903146多态位点分别进行基因分型,分析其与T2DM的相关性,同时检测临床指标,分析rs12255372-G/T和rs7903146-C/T多态性与T2DM、IR、脂代谢的相关性。结果:(1)两组rs7903146基因型及等位基因频率差异有统计学意义(P<0.01);两组rs12255372基因型及等位基因频率差异无统计学意义(P>0.05)。(2)T2DM组rs12255372位点及rs7903146位点不同基因型间比较FPG、FINS、HOMA-IR及HOMA-IS差异有统计学意义(P<0.01)。结论:在黑龙江省东部地区汉族人群中TCF7L2基因rs7903146-C/T多态性与T2DM有相关性;而rs12255372-G/T多态性与T2DM无相关性;TCF7L2基因rs12255372-G/T多态性和rs7903146-C/T多态性均与胰岛素抵抗相关。
