Novel genetic markers like microhaplotypes and compound markers show promising potential in forensic research. Based on previously reported single nucleotide polymorphism (SNP) and insertion/deletion (InDel) polymorphism loci, 29 genetic markers including 22 microhaplotypes and seven compound markers were identified. Genetic distributions of the 29 loci in five continental populations, Kazak and Mongolian groups in China were investigated. We found that the expected heterozygosity values of these 29 loci were >0.4 in these populations, indicating these loci were relatively high polymorphisms. Population genetic analyses of five continental populations showed that five loci displayed relatively high genetic variations among these continental populations and could be useful markers for ancestry analysis. In summary, the 29 loci displayed relatively high genetic diversities in continental populations and Chinese two groups and could be informative loci for forensic research.
新型遗传标记物,如微单倍型和复合标记物,在法医学研究中显示出了有前景的潜力。基于先前报道的单核苷酸多态性(SNP)和插入/缺失(InDel)多态性位点,鉴定出了 29 个遗传标记物,包括 22 个微单倍型和 7 个复合标记物。对中国五个大陆人群(哈萨克族和蒙古族群体)中的这 29 个位点的遗传分布进行了研究。我们发现,这些人群中这 29 个位点的预期杂合度值均>0.4,表明这些位点具有较高的多态性。对五个大陆人群的群体遗传学分析表明,五个位点在这些大陆人群之间表现出相对较高的遗传变异,可作为祖先分析的有用标记物。综上所述,这 29 个位点在大陆人群和中国两个群体中表现出相对较高的遗传多样性,可作为法医学研究的有用标记物。
