We genotyped 15 autosomal STRs loci in 1780 unrelated northeastern Thai individuals. Allele frequencies were computed and all of the loci reached Hardy-Weinberg equilibrium. The forensic parameter results showed high discrimination values which are suitable for forensic personal identification and paternity testing; the combined discrimination power and probability of excluding paternity were 0.9999999999999999999999 and 0.999998449, respectively. Genetic relatedness of northeastern Thais with comparable Thai and Asian populations using phylogenetic analysis revealed close genetic relationship between Mainland Southeast Asian populations and southern Chinese populations.
我们对 1780 名无亲缘关系的泰国东北部个体进行了 15 个常染色体 STR 基因座的基因分型。计算了等位基因频率，所有基因座均达到哈迪-温伯格平衡。法医学参数结果显示，高鉴别力值适用于法医个体识别和亲子鉴定；联合鉴别力和排除亲子关系的概率分别为 0.999999999999999999999 和 0.999998449。通过系统发育分析，与可比的泰国和亚洲人群进行的泰国东北部人群遗传关系研究表明，东南亚大陆人群与中国南方人群之间存在密切的遗传关系。
