Haplotype distribution of four new Y-STRs:DYS630, DYS631, DYS634 and DYS635 in aChinese population

摘要

In this study, we analyzed four new Y-STR loci, DYS630, DYS631, DYS634 and DYS635, investigated haplotype distributions of these Y-STR loci in a Chinese Han population (eastern China) and sequenced alleles of the four loci for clarifying the structure DYS630, DYS631 and DYS635 were found to be simple repeat systems, while DYS634 was complex repeat systems. The gene diversities of DYS630, DYS631, DYS634 and DYS635 were 0 797, 0 418, 0 459 and 0 809, respectively. A total of 50 different haplotypes was observed in 79 males. The haplotype diversity for all the four Y-specific STR loci in Chinese population was calculated to be 98 3% and the stand error (S.E) was calculated to be 0,3%. The results indicate that these four loci are useful Y-linked markets for forensic applications.
