ENPP1基因rs6925433位点基因多态性在喀什地区维吾尔族人群中的分布调查
|
Abstract:
摘要 目的:研究新疆喀什地区维吾尔族人群中焦磷酸合成酶1(ENPP1)基因rs6925433多态性位点的分布特征。方法:采用横断面研究方法,以喀什地区疏附县213例维吾尔族个体为对象,采用棉拭子法取双侧颊黏膜脱落上皮细胞,提取基因组DNA,利用PCR和双脱氧末端终止法基因测序,结合DNAstar和Chromas 2等软件进行基因分型,统计分析受试人群基因型频率和等位基因频率,并与已报道的其他地区民族基因数据进行比较分析。结果:喀什地区维吾尔族人群中ENPP1基因rs6925433位点GG,AG和AA的基因型频率分布分别为28.17%,50.23%和21.60% ,A/G等位基因频率分布A=46.71%,G=53.29%;与北京汉族人群相比,维吾尔族人群rs6925433位点GG型分布高,AA型分布低(P=0.046);与欧洲人群相比,维吾尔族人群该SNP位点GG型分布低,AA型分布高(P=0.010),差异均具有统计学意义;在上述3个人群中,A/G等位基因频率分布未见明显差别。结论:新疆喀什地区维吾尔族人群与其他民族人群rs6925433位点基因多态性分布特征明显不同
