12 Y-STRs haplotypes in Chinese Naxi ethnic minority group

Twelve Y-STRs loci including minimal haplotypes (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, and DYS385a,b) and three additional loci, namely DYS437, DYS438 and DYS439 were co-amplified in 138 healthy unrelated males of Chinese Naxi ethnic minority group using the PowerPlex Y System. A total of 113 haplotypes were identified, among which 103 were unique, and 6, 2, 1 and 1 were found in 2, 4, 5 and 10 individuals, respectively. The haplotype diversity for 12 Y-STRs loci was 0.9923.The results from the present study can be used in forensic application and population genetics in the region, and can enrich Chinese ethnical genetic informational resources.
