-
摘要:
目的 对中国云南省基诺族人群无关个体进行 17个 STR 基因座遗传多态性调查,评估数据在人群中的法医学应用价值。 方法 检验331例基诺族无关个体,用AGCU 17+1试剂盒进行STR基因型扩增检测,使用ABI3130毛细管电泳仪分离扩增产物片段并进行等位基因分型。 结果 共检出186个等位基因,等位基因频率分布在 0.0015 ~0.5619 ,TPOX、TH01基因座多态性和识别能力最低,D3S1358、D13S317、D16S539、CSF1PO、D5S818均有参数显示多态性不佳,其他基因座显示有较好的多态性。基因型分布均符合哈温平衡,CDP和CPE均显示有较好的识别度。结论 除TPOX和TH01基因座,其余的15个常染色体STR 基因座在基诺族群体中具有较好的多态性,可以满足法医个体识别和亲权鉴定应用。 Abstract:Objective To study the genetic polymorphism of 17 autosomal STR loci in the Jino people of Yunnan, and to evaluate its value in forensic medicine. Methods A total of 331 unrelated individuals of the Jino people in Yunnan Province were examined. AGCU 17+1 kit was used for STR genotyping, and ABI3130 capillary electrophoresis apparatus was used to isolate the amplified product fragments and to determineallele type . Results A total of 186 alleles were detected, and the allele frequencies ranged from 0.0015 to0.561 9 . TPOX and TH01 loci had the lowest polymorphism and recognition ability, and D3S1358, D13S317, D16S539, CSF1PO and D5S818 had poor polymorphism parameters. Other loci showed better polymorphism. The distribution of genotypes was in accordance with Hardy-Weinberg equilibrium, and CDP and CPE showed good recognition.Conclusion Except for TPOX and TH01, the remaining 15 autosomal STR loci have good polymorphism in Jino population, which can meet the application of forensic individual identification and paternity identification. Except the TPOX and TH01 loci, the remaining 15 autosomal STR loci have good polymorphisms in the Jino population. -
