Abstract
Previously, we developed and validated a multiplex assay of 27 ancestry-informative markers (AIMs) for analyzing African (AFR), European (EUR), and East Asian (EAS) ancestry components. In this study, we typed and collectively analyzed a large Uyghur sample of 979 individuals to estimate the genetic coefficients of the 27 AIMs and investigate differentiation parameters between Uyghur and Han. The Uyghur allele frequencies ranged from 0.243 to 0.952, and heterozygosities ranged from 0.091 to 0.500. Values of F st3 and I n3 for EUR, Uyghur, and EAS ranged from 0.028 to 0.550 and 0.0002 to 0.345, respectively. The Uyghur population displays a substantial ancestry contribution of 50.3:49.7 (EUR:EAS) and was efficiently discriminated from Han Chinese with an accuracy of 99.285 %. All populations were clustered into AFR, EUR, EAS, and admixture groups of these three ancestries. Central Asian was obviously stratified from the other admixture populations of South Asians, North Asians, and the Americans. The 27 SNPs yield a circle with an average distance of 0.936 from the center (0, 0) in PCA analysis. Using this set, Chinese Uyghur and Han populations achieved accurate differentiation, and our updated genotype database (by citing 1000 Genomes data) of 43 worldwide populations is a useful resource for forensic applications and disease association studies.
