摘要:

目的 研究新疆维吾尔族人群16个X-STR基因座的遗传多态性和群体遗传学参数。 方法 应用Goldeneye? DNA身份鉴定系统17X对502例(女性251例,男性251例)新疆维吾尔族无关个体进行16个X-STR基因座的复合扩增,应用3130xl基因分析仪对扩增产物进行检测,并统计等位基因频率及群体遗传学参数,计算维吾尔族与其他8个人群间的遗传距离,并根据遗传距离进行多维尺度分析以及系统发育树的构建。 结果 在502例新疆维吾尔族无关个体中,所检测的16个X-STR基因座共观察到67个等位基因,等位基因频率为0.001 3~0.572 4,PIC为0.568 8~0.855 3,女性CDP为0.999 999 999 999 999,男性CDP为0.999 999 999 743 071,三联体累积平均非父排除率为0.999 999 997 791 859,二联体累积平均非父排除率为0.999 998 989 000 730。维吾尔族人群与哈萨克族人群遗传距离较近,与汉族人群遗传距离较远。 结论 该16个X-STR基因座在维吾尔族人群中具有高度的多态性和较好的鉴别能力,可为该人群的法医学个体识别、亲权鉴定和群体遗传学研究提供有力的补充。

Abstract:

Objective To study the genetic polymorphism and population genetic parameters of 16 X-STR loci in Xinjiang Uygur population. Methods The Goldeneye? DNA identification system 17X was used to amplify 16 X-STR loci in 502 unrelated individuals (251 females and 251 males). The amplified products were detected by 3130xl genetic analyzer. Allele frequencies and population genetic parameters were analyzed statistically. The genetic distances between Uygur and other 8 populations were calculated. Multidimensional scaling and phylogenetic tree were constructed based on genetic distance. Results In the 16 X-STR loci, a total of 67 alleles were detected in 502 Xinjiang Uygur unrelated individuals. The allele frequencies ranged from 0.001 3 to 0.572 4. PIC ranged from 0.568 8 to 0.855 3. The cumulative discrimination power in females and males were 0.999 999 999 999 999 and 0.999 999 999 743 071, respectively. The cumulative mean paternity exclusion chance in trios and in duos were 0.999 999 997 791 859 and 0.999 998 989 000 730, respectively. The genetic distance between Uygur population and Kazakh population was closer, and the genetic distance between Uygur and Han population was farther. Conclusion The 16 X-STR loci are highly polymorphic and suitable for identification in Uygur population, which can provide a powerful supplement for the study of individual identification, paternity identification and population genetics.
