摘　　要：目的探讨亚甲基四氢叶酸还原酶(MTHFR)基因C677T位点单核苷酸多态性与原因不明复发性流产(URSA)的发生之间的相关性。方法采用前瞻性病例对照研究,选取清远地区71例URSA患者与76例两次正常生育妇女作为对照,采用实时定量PCR分析技术检测MTHFR基因C677T位点单核苷酸多态性情况,并用χ^2检验分析URSA组与对照之间的C677T位点基因型的差异。结果 URSA组MTHFR(C677T)基因纯合突变型TT及等位基因T的频率均高于正常对照组。结论清远地区不明原因复发性流产的发生与MTHFR基因C677T位点纯合突变型TT存在相关性。Objective:To investigate the correlation between single nucleotide polymorphism(SNP)at C677T locus of methylenetetrahydrofolate reductase(MTHFR)gene and unexplained recurrent abortion(URSA).Methods:A prospective case-control study was conducted.71 URSA patients and 76 normal births women in Qingyuan area were selected as controls.The SNP at C677T locus of MTHFR gene was detected by real-time quantitative PCR analysis,genotype differences at C677T locus between URSA group and control group were analyzed by χ^2 test.Results:The frequency of homozygous TT and T allele of MTHFR(C677T)gene in URSA group was higher than that in normal control.Conclusion:The occurrence of unexplained recurrent abortion in Qingyuan is correlated with homozygous TT at C677T locus of MTHFR gene.
