Allele frequencies for six miniSTR loci of two ethnic populations in China

Allele frequencies and forensic parameters for the six miniSTR loci D1S1677, D2S441, D4S2364, D10S1248, D14S1434, and D22S1045 were investigated in two ethnic China populations. Allele frequencies for each locus are reported along with nomenclature based on sequence analysis. The polymerase chain reaction (PCR) products contained within the six loci were less than 125 bp in size. All loci showed a moderate degree of polymorphism with observed heterozygosity >0.7 except for D4S2364 and did not show departures from Hardy–Weinberg equilibrium for all two populations. The accumulated powers of discrimination for the six loci were 0.999994, and 0.999996 for Han ethnic, and Korean ethnic minority group, respectively.
