Analysis of 27 Y-chromosomal STR haplotypes in a Han population of Henan province, Central China

Abstract

A total of 1225 unrelated Han males from Henan province were analyzed with the prototype Yfiler® Plus kit (Life Technologies, Thermo Fisher Scientific, Waltham, MA, USA). The calculated gene diversity (GD) values ranged from 0.3855 to 0.9673 for the DYS391 and DYS385a/b loci, respectively. The discriminatory capacity (DC) was 86.94 % with 1065 observed haplotypes using 17 Yfiler loci, by the addition of 10 Y-STRs to the Yfiler® Plus system, the DC was increased to 98.94 % while showing 1212 observed haplotypes. Among the new incorporated Y-STRs, DYS576, DYF387S1, DYS518, DYS627, and DYS449 were major contributors to enhancing discrimination. In the analysis of molecular variance, the Henan Han population clustered with Asian origin populations and showed significant differences from other reference populations. In this study, the improvement of adding additional Y-STR markers with the Yfiler® Plus kit provided substantially stronger discriminatory power in the Henan Han population.
