摘要: 目的 调查福建汉族人群21个常染色体STR基因座多态性参数,评估GlobalFilerTM Express试剂盒的法医学应用价值。 方法 应用GlobalFilerTM Express试剂盒复合扩增检测741名福建汉族无关个体,计算21个常染色体STR基因座的群体遗传学参数。 结果 21个常染色体STR基因座的基因型分布均符合Hardy-Weinberg平衡(P>0.05),21个STR遗传标记均具有高度多态性,杂合度为0.589~0.914,个体识别率为0.754~0.992,多态信息含量为0.520~0.940,非父排除率为0.278~0.825。其中以SE33基因座多态性程度最高。 结论 GlobalFilerTM Express试剂盒的21个STR基因座有较强的系统效能,该试剂盒可应用于福建汉族人群的法医学个体识别及亲权鉴定。

Abstract: Objective To investigate the genetic polymorphisms of 21 autosomal STR loci of Fujian Han population and evaluate the forensic application value of GlobalFilerTM Express kit. Methods Amplified with GlobalFilerTM Express kit, DNA samples were obtained from 741 unrelated individuals of Fujian Han population. The population genetics parameters of 21 autosomal STR loci were calculated. Results The 21 autosomal STR loci were found to be no deviation from Hardy-Weinberg equilibration (P>0.05) and relatively abundant in high polymorphism. Heterozygosity ranged from 0.589 to 0.914, power of discrimination ranged from 0.754 to 0.992, polymorphic information content ranged from 0.520 to 0.940, and power of exclusion ranged from 0.278 to 0.825. The SE33 locus was the highest degree in polymorphism. Conclusion The 21 STR loci of GlobalFilerTM Express kit have high value in discrimination power and can be useful in personal identification and paternity test in Fujian Han population.
