Abstract

Ili is located in northernmost Xinjiang, China. The Uyghur population only accounts for 15.90% of the total population in the nation. There is currently no large population data-based data set in Ili Uyghur. In this study, we investigated the genetic diversities of 18 autosomal short tandem repeat (STR) loci in 1129 Uyghur individuals living in Ili. The values of combined power of discrimination (CPD) and combined probability of exclusion (CPE) were 0.99999999999999999999990244 and 0.99999995645, respectively. Furthermore, we explored the genetic relationships between the Ili Uyghur population and 32 previously published populations. The results indicated that the Ili Uyghur population was more closely related to the Xinjiang Kazakh population. In addition, It was worth noting that significant differences were observed between Ili the Uyghur population and the Uyghur1 and Uyghur2 populations at the shared 15 loci, with significant differences at 7 and 11 loci after Bonferroni adjustment (p = 0.05/495 ≈ 0.00010).
