【摘要】 目的 了解宁夏回族甲硫氨酸合酶(MS)基因A2756G的多态性的分布特点。方法 通过聚合酶链式反应-限制性片段长度多态性(PCR-RFLP)技术分析200例宁夏回族MS基因A2756G基因型。结果 宁夏回族人群中AA、AG、GG基因型频率分别为0.8100、0.1750、0.0150,G突变基因频率为0.1025。与白种人群中的分布差异有统计学意义(P<0.05)。结论 甲硫氨酸合酶基因A2756G基因型在不同种族间的分布存在明显的差异。

Methods Genotypes were determined by using polymerase chain reaction-restrict fragment length polymorphism(PCR-RFLP). Results Methionine synthase genetype frequency in Ningxia Hui was AA0.8100,AG0.1750,GG0.0150. The frequency of G was 0.1025,which was significantly different from that of white people(P<0.05). Conclusion The MS genes A2756G distribution in Hui Nationality Population is different from those in other areas.
