Forensic features for Yunnan Lisu ethnic minority and phylogenetic structure exploration among 26 Chinese populations

The genetic polymorphisms of 15 autosomal short tandem repeat (STR) loci included in the AmpFlSTR®Sinofiler™ kit were evaluated from 508 unrelated healthy individuals of the Lisu ethnic minority living in Chuxiong Yi Autonomous Prefecture, Yunnan province, southwest of China. Fourteen of the 15 loci reached the Hardy–Weinberg equilibrium after Bonferroni correction. These loci were examined to determine allele frequencies and forensic statistical parameters. The genetic relationship between the Lisu population and other Chinese populations were also estimated. The combined discrimination power and probability of excluding paternity of the 15 STR loci were 0.999 999 999 999 999 999 654 and 0.999 998 882, respectively. These results suggest that the 15 STR loci are highly polymorphic, which is suitable for forensic personal identification and paternity testing.
