Aim: To investigate the genetic polymorphism of a new multi-copy locus DYF399S1 on Y chromosome among Han population in Henan Province.Methods: The products amplified using fluorescent-PCR from 248 unrelated Henan Han males were separated and the allelic fragments were sequenced on ABI 3130 genetic analyzer.Results:DYF399S1 was a three-copies locus.The core sequence was GAAA and the alleles were from 12 to 22.The motif of DYF399S1 locus included 1 stable and 1 variant repeat structure,namely,( GAAA)3N7( GAAA)12-22.A total of 94 haplotypes were identified among 248 unrelated men from Henan Han populations.Out of them,the most frequent haplotype was18 /18 /18 and the frequency was 0.080 6; 49 types were observed once only and the frequency was 0.004 0.The discrimination capacity( DC) was 0.372 5,and the haplotype diversity and the discriminating power were 0.865 5 and 0.862 1,respectively.Conclusion: DYF399S1 locus is a highly polymorphic marker and useful for applying to forensic medicine and human evolution study.
