Allele Frequencies of 19 Autosomal STR Loci in Manchu Population of China with Phylogenetic Structure Among Worldwide Populations

The aim of this study was to estimate the allelic frequencies of the 19 STR loci with the Goldeneye™ DNA ID system 20A kit in a sample of 150 Manchu individuals from China to be used for forensic purposes and population studies. The observed heterozygosity(HO)values of these 19 STR loci ranged from 0.600 (D3S1358) to 0.914 (D18S51), the expected (HE) ranged from 0.615 (TPOX) to 0.876 (D16S1043). The power of discrimination (PD) values were found to range from 0.793 (TPOX) to 0.950 (D16S1043) and the probability of exclusion (PE) varies between 0.291 (D3S1358) and 0.825 (D18S51 and Penta E). Among all the 19 loci, D16S1043 had the highest polymorphism (PIC=0.860), whereas TPOX had the lowest (PIC=0.550). For the 19 loci, the combined power of discrimination and the combined probability of exclusion are 0.9999999999999999999942 and 0.999999996777, respectively. The phylogenetic tree established among worldwide population shows different populations who say the same language usually have a close genetic relationship with each other across the three language families studied (Sino-Tibetan, Altaic and Arabic).
