摘要 目的:分析河北省三河市汉族育龄女性叶酸代谢相关酶5,10-亚甲基四氢叶酸还原酶(MTHFR)和甲硫氨酸合成酶还原酶( MTRR)的基因多态性分布特征,以指导育龄女性增补叶酸和出生缺陷一级预防。方法以三河市601例汉族育龄女性为研究对象,以其口腔黏膜上皮细胞提取基因组DNA,通过荧光定量PCR法对MTHFR和MTRR的多态性位点进行分析,获得三河市汉族育龄女性该基因的分布特征,并与已报道的其他地区的数据进行比较。结果三河市汉族育龄女性的 MTHFR 677TT 纯合突变基因型频率(37.40%),高于延边市(28.30%)、镇江市(21.84%)、松滋市(15.40%)、德阳市(13.80%)、惠州市(10.90%)、琼海市(6.14%),低于淄博市(43.6%)(χ2=12.60、87.44、151.95、233.02、161.87、446.90、7.27,均P<0.05)。 MTHFR 1298CC纯合突变基因型频率(2.30%),高于淄博市(1.44%),低于镇江市(3.50%)、松滋市(2.60%)、德阳市(6.26%)、惠州市(7.20%)、琼海市(7.13%)(χ2=5.84、6.49、14.32、32.54、22.94、53.12,均P<0.05)。 MTRR 66GG纯合突变基因型频率(7.50%)低于琼海市(9.25%)(χ2=16.34,P<0.05),高于松滋市(6.40%)(χ2=4.10,P<0.05)。结论三河市汉族育龄女性MTHFR和MTRR基因多态性频率分布具有地域特异性。 Objective To explore the genotype distribution of methylenetetrahydrofolate reductase ( MTH-FR)C677T,A1298C and methionine synthase reductase (MTRR) A66G involved in the folic acid biosynthetic path-way among Chinese Han gestational age women in Sanhe City .Methods 601 samples were recruited from Sanhe re-gion,genomic DNA was obtained from the oral mucosa cells .The detections of MTHFR and MTRR gene polymor-phisms conducted with Taqman -MGB technology .The distribution of gene polymorphisms of this study was analyzed and compared with partial regions of China ,which were reported.Results The frequency of MTHFR 677TT among Sanhe women(37.40%) was significantly different to Yanbian (28.30%),Zhenjiang(21.84%),Songzi(15.40%), Deyang(13.80%),Huizhou(10.90%),Qionghai(6.14%),Zibo(43.6%) (χ2 =12.60,87.44,151.95,233.02, 61.87,446.90,7.27,all P〈0.05).The frequency of MTHFR 1298CC(2.30%) was significantly different to Zibo (1.44%),Zhenjiang(3.50%),Songzi(2.60%),Deyang(6.26%),Huizhou(7.20%),Qionghai(7.13%) (χ2 =5.84,6.49,14.32,32.54,22.94,53.12,all P〈0.05).The frequency of MTRR 66GG (7.50%) was significantly different to Qionghai (9.25%),Songzi(6.40%)(χ2 =16.34,4.10,all P〈0.05).Conclusion The MTHFR, MTRR polymorphism distribution of Han women in Sanhe City is region specific ,respective .
