【摘要】:目的:调查南昌地区汉族人群无关个体TPOX、vWA、D7S820、D5S818、CSFIPO、D16S539 等6 个STR 基因座的遗传多态性。 方法:应用PCR及PAGE技术检测南昌地区120例汉族无关个体TPOX、vWA、D7S820、D5S818、CSFIPO、D16S539 等6 个STR 基因座的等位基因。 结果:在120 例南昌地区汉族人群中,TPOX 基因座,观察到5 个等位基因,11 种基因型;vWA 基因座,观察到7 个等位基因,22 种基因型;D7S820 基因座,观察到6 个等位基因,20 种基因型;D5S818 基因座,观察到8 个等位基因,21 种基因型;CSFIPO 基因座,观察到6 个等位基因,18 种基因型;D16S539 基因座,观察到7 个等位基因,24 种基因型。TPOX、vWA、D7S820、D5S818、CSFIPO、D16S539 等6 个基因座的观察杂合度(Ho)分别为:0.5882、0.7414、0.7982、0.7522、0.8034、0.8364;期望杂合度(He)分别为:0.6108、0.8063、0.7880、0.7801、0.7504、0.7993;个人识别率(DP)分别为:0.6082、0.7993、0.7810、0.7766、0.7472、0.7956;非父排除率(PE)分别为: 0.3986、0.633、0.5958、0.5818、0.5464、0.6226;多态信息含量(PIC)分别为: 0.5989、0.7917、0.7618、0.7540、0.7248、0.7817。 结论:TPOX 等6 个基因座的基因频率在南昌地区汉族人群的分布符合Hardy-Weinberg 平衡,且遗传多态性高,与中国其它地区人群等位基因分布频率比较无显著性差异(P0.05),为南昌地区法医学亲子鉴定和
[Abstract]:Objective: to investigate the genetic polymorphism of 6 STR loci such as D7S820, D5S818 and CSFIPOD16S539 in unrelated individuals of Han nationality in Nanchang area.Methods: PCR and PAGE techniques were used to detect the alleles of 6 STR loci such as D7S820, D5S818, CSFIPOU D16S539 in 120 unrelated individuals of Han nationality in Nanchang area.Results: TPOX loci were observed in 120 Han population in Nanchang, 5 alleles were observed in 11 genotypes, 7 alleles were found in 22 genotypes, and 6 alleles were detected in 20 genotypes, including D5S818 loci.Eight alleles, 21 genotypes of CSFIPO loci, and 6 alleles of 18 genotypes, D16S539, were observed.瑙傚療鍒,
