目的了解云南傣族３个ＳＴＲ位点遗传多态性分布。方法应用多重ＰＣＲ技术对ＨＵＭＣＳＦ１ＰＯ、ＨＵＭＴＰＯＸ和ＨＵＭＴＨ０１３个ＳＴＲ基因座进行分析，采用高分辨率的聚丙烯酰胺凝胶电泳分离、银染法显影技术，对云南傣族上述３个基因座进行遗传多态性调查。结果ＣＳＦ１ＰＯ位点，观察到７个等位基因，１５个基因型；ＴＰＯＸ位点，观察到７个等位基因，１８个基因型；ＴＨ０１位点，观察到６个等位基因，１７个基因型。结论上述３个短串联重复序列基因座基因频率分布与Ｈａｒｄｙ－Ｗｅｉｂｅｒｇ平衡吻合良好。
Objective To understand the genetic polymorphism distribution of three STR loci in Yunnan Dai nationality. Methods Multiplex PCR (PCR) was used to analyze the STR loci of HUMCSF1PO, HUMTPOX and HUMTH013. High-resolution polyacrylamide gel electrophoresis and silver staining were used to detect the genetic polymorphism of these three loci in Yunnan province. survey. Results There were 7 alleles and 15 genotypes in the CSF1PO locus. Seven TP alleles and 18 genotypes were observed in the TPOX locus. Th01 alleles, 6 alleles and 17 genes were observed type. Conclusion The frequency distribution of the three short tandem repeat loci was in good agreement with Hardy-Weiberg equilibrium.
