Haplotypes for 12 Y-chromosomal STR loci in a Korean population (the central region).

Haplotypes and allele frequencies of 12 STR loci included in the PowerPlex Y system (DYS391, DYS389I, DYS439, DYS389II, DYS438, DYS437, DYS19, DYS392, DYS393, DYS390, and DYS385a/b) were obtained from a sample of 569 unrelated individuals living in the central region of Korea. A total of 473 haplotypes were observed in the 569 individuals studied, of which 426 (90.06%) were unique. The overall haplotype diversity for the 12 Y-STR loci was 0.9985, and the discrimination capacity was 0.8313. In DYS439, we found a new intermediate-sized allele that added an A at base 3 upstream from the repeat region's first GATA motif. The allele was named 11 (U3Ains) according to its sequence structure.
