Y-chromosomal short tandem repeat (Y-STR) loci can play important roles in forensic casework and paternity testing. In our paper, 24-plex Y-STR typing system, which includes 3 loci (DYS635 and DYS385a/b) existed in current widely available commercial kits and 21 additional loci (DYS531, DYS630, DYS622, DYS552, DYS510, DYS449, DYS459a/b, DYS446, DYS443, DYS587, DYS527a/b, DYS460, Y-GATA-A10, DYS520, DYS557, DYS522, DYS481, DYS570, DYS444) was established with 5-dye fluorescence labeling. 200 unrelated Chinese Han males were successfully genotyped with the system and 198 haplotypes were observed. The gene diversity of each locus ranged from 0.55 (DYS531) to 0.96 (DYS385a/b), the haplotype of diversity was 0.9998 for these 24 Y-STR loci. The established 24-plex Y-STR typing system is proved to be stable and efficient in forensic DNA typing. (C) 2013 Elsevier Ireland Ltd. All rights reserved.
