Population genetic polymorphisms of 17 Y-chromosomal STR loci in South Koreans.

Haplotypes and allele frequencies of 17 Y-chromosomal STR loci included in the AmpFlSTR(®) Yfiler(®) system were obtained from a sample of 1021 unrelated individuals living in 6 provinces of South Korea. A total of 938 haplotypes were observed in the 1021 individuals studied, of which 885 were unique. The overall haplotype diversity for the 17 Y-STR loci was 0.9998, and the discrimination capacity was 0.9187. We found 11 atypical alleles (null, duplicated, triplicated, and microvariant alleles), that have not previously been reported in South Korean populations. It seems that these 17 loci are useful genetic markers for forensic personal identification and paternity testing in the South Korean population.
