摘　　要：目的调查南方汉族、黎族人群无关个体的15个STR基因座(D8S1179、D21S11、D7S820、CSF1PO、D3S1358、TH01、D13S317、D16S539、D2S1338、D19S433、vWA、TPOX、D18S51、D5S818、FGA)多态性,研究其在法医学检验中的应用价值。方法应用AmpFlSTRIdentifilerTM荧光标记复合扩增系统对南方332例汉族、334例黎族无关个体血样DNA进行15个STR基因座的复合扩增,用ABI3100遗传分析仪对扩增产物进行检测,用GeneScan、GenoTyper软件进行基因分型,统计计算15个STR基因座的群体遗传学参数。结果IdentifilerTM荧光标记系统的15个STR基因座在南方汉族、黎族人群的累积偶合率分别为4.94×10-17、2.50×10-17,累积非父排除率分别为0.9999989、0.9999988。结论该15个STR基因座足可满足南方汉族、黎族法医学的个体识别及亲权鉴定的需要。Objective The study was carried out on investigating genetic polymorphism of15STR loci in southern China Han population and Li population.Methods DNA samples from332unrelated individuals of southern China Han population and334individuals of Li population were screened by using AmpFlSTR Identifiler TM PCR Amplification Kit and3100Genetic Analyzer.Results These15loci met the Hardy-Weinberg expectations.The matching probability of the15STR loci was4.94 × 10 -17 ?2.50 × 10 -17 and com bined paternity of exclution was0.9999989?0.9999988in the two population.Conclusion Our results showed Identifiler TM PCR Amplification systems of15STR loci were useful to forensic case work in south ern China Han population and Li population.
