云南23个少数民族人群腺苷酸激酶(AK1)多态分布调查

采用淀粉凝胶电泳法,对云南彝、白、哈尼、壮、傣、苗、傈僳、回、拉祜、佤、纳西、瑶、藏、景颇、布朗、普米、怒、阿昌、德昂、基诺、布依、独龙和苦聪人等23个少数民族人群的红细胞腺苷酸激酶(AK1)的多态分布进行了调查。结果,在23个人群中均未检出AK21纯合子。但在彝、回、景颇、布朗、怒和德昂6个民族中检出了AK21杂合子,AK21基因频率在这6个民族中的分布在0.0045-0.0446之间,其中,仅回族的AK21基因达多态水平。 Abstract:The investigation on the distribution of adenylate kinase(AK1)polyorphism in 23 ethnic groups in Yunnan province of China,including the minorities of Yi,Bai,Hani,Zhuang,Dai,Miao,Lisu,Hui,Lahu,Wa,Naxi,Yao,Tibetan,Jingro,Bulang,Pumi,Nu,Achang,Deang,Jino,Buyi,Dulong and Kucong people,was carried out,using starch gel electrophoresis.The results showed that no AK21,homozygote and other variations were found.But AK21 heterozygotes were found in the minorities of Yi,Hui,Jingpo,Bulang,Nu and Deang.The ranges of AK21 gene frequencies were 0.0045-0.0446.     

云南汉族人群D17S30位点扩增片段长度多态性A

应用PCR技术和小型聚丙烯酰胺凝胶电泳银染法, 对云南汉族人群D17S30位点扩增片段长度多态性进行了分析。在被检的105名无关个体中,共检出12个等位基因,41种基因型。等位基因频率范围在0.0048-0.2190之间,杂合度为83.81%,DP值为0.9647。观察的基因型分布符合Hardy-Weinber g定律。 Abstract:A study on amplified fragment length polymorphism(Amp-FLP)at locus D17S30 in Han nationality of Yunnan was carried out by using PCR followed by a high-resolution PAGE technique and silver staining.In a sample of 105 unrelated individuals,a total 12 different alleles and 41 genotypes were detected.The heterozygosity was 83.81% and the probability of discrimination(DP) was 0.9647.The distribution of observed genotypes obeyed the Hardy-Weinberg equilibrium.
