摘要: 目的 调查山东汉族人群19个STR基因座的群体遗传学资料,为亲权鉴定提供遗传学数据。 方法 采用GoldeneyeTM 20A试剂盒对山东汉族人群中205例无关个体进行基因分型,得到19个STR基因座的等位基因频率及群体遗传学参数。对IdentifilerTM、SinoFilerTM、PowerPlex 16和GoldeneyeTM 20A 4个试剂盒进行比较,并对1例特殊的亲子鉴定案件进行分析。 结果 获得山东汉族人群19个STR基因座的群体遗传学参数。累积个体识别率(CDP)及累积非父排除率(CPE)从高到低分别为GoldeneyeTM 20A、SinoFilerTM、PowerPlex 16、IdentifilerTM试剂盒。对实际案件进行分析,作为二联体,IdentifilerTM试剂盒无被排除基因座,而SinoFilerTM、PowerPlex?誖16和GoldeneyeTM 20A试剂盒均不能排除父子关系。 结论 与IdentifilerTM、SinoFilerTM和PowerPlex?誖16 3种试剂盒进行比较,GoldeneyeTM 20A试剂盒效能更高,但不能完全满足二联体鉴定的要求。

Abstract: Objective To investigate the genetic polymorphisms of 19 STR Loci in Shandong Han population in order to provide the genetic data for paternity testing. Methods The genotypes of 205 unrelated individuals in Shandong Han population were typed by GoldeneyeTM 20A kit to get the allele frequencies and population genetic parameters of 19 STR loci. Four kits, IdentifilerTM kit, SinoFilerTM kit, PowerPlex 16 kit, and GoldeneyeTM 20A kit, were compared with each other and used in the analysis of a special paternity test case. Results The population genetic parameters of 19 STR loci in Shandong Han Population were obtained. The cumulative discrimination power (CDP) and cumulative probability of exclusion (CPE) ranked from high to low were GoldeneyeTM 20A kit, SinoFilerTM kit, PowerPlex 16 kit and IdentifilerTM kit, respectively. As duo case, the result of the real case showed that IdentifilerTM kit had no excluding loci, and none of the SinoFilerTM kit, PowerPlex 16 kit or GoldeneyeTM 20A kit could exclude fatherhood. Conclusion Compared with IdentifilerTM kit, SinoFilerTM kit, and PowerPlex 16 kit, GoldeneyeTM 20A kit shows the higher efficiency than the others, but is not completely satisfied for duo cases.
