摘要: 目的 调查GoldeneyeTM DNA身份鉴定系统22NC试剂盒中所包含的21个常染色体STR基因座在汉族人群中的遗传学数据,并考察该试剂盒的法医学应用价值。 方法 应用GoldeneyeTM DNA身份鉴定系统22NC试剂盒对华东地区500名汉族健康无关个体进行常染色体STR基因座分型检测,统计分析21个常染色体STR基因座的频率数据、群体遗传学参数及连锁不平衡状况。 结果 21个常染色体STR基因座在华东汉族人群中均符合Hardy-Weinberg平衡,各基因座之间相互独立。DP值均大于0.85,在群体中的CDP值为1-3.616 5×10-26,二联体累积非父排除率为1-2.786 81×10-6,三联体累积非父排除率为1-8.545 82×10-10。 结论 GoldeneyeTM DNA身份鉴定系统22NC试剂盒中所包含的21个常染色体STR基因座在华东汉族人群中具有良好的多态性,联合GoldeneyeTM DNA身份鉴定系统20A可以满足双亲皆无的全同胞鉴定要求,为该类案件的解决提供便利的工具。

Abstract: Objective To investigate the genetic data of 21 autosomal STR included in GoldeneyeTM DNA ID 22NC Kit in Chinese Han nationality and to evaluate the forensic application. Methods By detected 500 unrelated healthy individuals in Chinese Han nationality of East China with GoldeneyeTM DNA ID 22NC Kit, allele frequencies, population genetics parameters and linkage disequilibrium information of the 21 autosomal STR were statistically analyzed. Results In the 21 autosomal STR, no deviations from Hardy-Weinberg equilibrium were detected and all loci were independent form each other. DP values of 21 autosomal STR were all above 0.85, and the combined discrimination power was 1-3.616 5×10-26. Combined mean exclusion chance of this system in duo cases was 1-2.786 81×10-6, in trio cases was 1-8.545 82×10-10. Conclusion Twenty-one autosomal STR included in GoldeneyeTM DNA ID 22NC Kit are highly polymorphic in the Han nationality. Combined with GoldeneyeTM DNA ID 20A Kit, the kit can satisfy the needs for full-sibling testing and facilitate the solution of this kind of case tools.
