Allelic frequencies of fifteen autosomal STRs in the northeastern Thai people

Abstract

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.
