Genetic polymorphism of 15 Y chromosomal STR loci and haplotypes of Henan Han population.

We studied and established a DNA database of 15 Y-STRs (DYS438, DYS446, DYS391, DYS390, DYS458, DYS534, DYS426, DYS626, DYS504, DYS505, DYS576, DYS532, DYS594, DYS522, DYS540) in a population sample of 102 unrelated, healthy, male individuals of Henan Han population. Allelic frequencies and statistical parameters of Han population were calculated. Totally 90 alleles were observed, with the corresponding allelic frequencies ranging from 0.0098 to 0.9020. 102 haplotypes were found in the studied group, the haplotype diversity for 15 Y-STR loci was 1. The results of present study were valuable for human identification and paternity tests routine forensic applications in the region.
