摘要 目的:探讨代谢叶酸的亚甲基四氢叶酸还原酶(MTHFR C 677 T)基因单核苷酸多态性与乳腺癌的关系。方法:以聚合酶链反应和限制性片段长度多态方法,分析了65个乳腺癌患者和性别、年龄配对的143个正常对照的MTHFR C 677 T基因型及其对乳腺癌的相关性。结果:在正常对照中,MTHFR C 677 T C C、CT、TT基因型频率分别为62.9%、35.08%和2.12%,MTHFR C 677 T C、T基因型频率分别为:0.8040,0.1960。而在乳腺癌患者中分别为58.46%、26.15%和15.39%,MTHFR C 677 T C、T基因型频率分别为:0.7154,0.2846。MTHFR C 677 T基因型在病例和对照中的分布差异无显著性。结论:MTHFR C 677 T单核苷酸多态可能与乳腺癌的遗传易感性无关。
