Y染色体短串联重复序列(Y-STR)基因座在法医学案件调查和亲子鉴定中具有重要作用。本研究建立了一套24重Y-STR分型系统,包括3个基因座,(DYS 635和DYS 385 a/B)和21个额外的基因座(DYS531、DYS630、DYS622、DYS552、DYS510、DYS449、DYS459a/B、DYS446、DYS443、DYS587、DYS527a/B、DYS460、Y-GATA-A10、DYS520、DYS557、DYS522、DYS481、DYS570、DYS572、DYS573、DYS574、DYS575、DYS576、DYS577、DYS578、DYS579、DYS587、DYS 444)进行5-染料荧光标记。应用该系统对200名无关汉族男性进行了基因分型,共观察到198种单倍型。24个Y-STR基因座的基因多样性在0.55(DYS 531)~ 0.96(DYS 385 a/B)之间,单倍型多样性为0.9998。建立的24重Y-STR分型系统稳定、高效。(C)2013爱思唯尔爱尔兰有限公司版权所有。
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.
