In this study, we analyzed DNA samples from 213 Japanese father son pairs with 25 Y-chromosome short tandem repeat (Y-STR) (DYS576, DYS389I, DYS635, DYS389II, DYS627, DYS460, DYS458, DYS19, YGATAH4, DYS448, DYS391, DYS456, DYS390, DYS438, DYS392, DYS518, DYS570, DYS437, DYS385, DYS449, DYS393, DYS439, DYS481, DYF387S1, and DYS533) markers using the Yfiler™ Plus PCR amplification kit. We calculated Y-STR mutation rates for each locus to evaluate the efficacy of the 25 Y-STR markers for paternity testing and forensic identification using samples from male relatives. Six rapidly mutating Y-STR markers (DYS576, DYS627, DYS518, DYS570, DYS449 and DYF387S1), previously reported to have high mutation rates (>1.0 × 10), are included in the 25 Y-STR markers, but our findings revealed that the mutation rates for all Y-STR markers except for DYS576 and DYS458 were lower than 1.0 × 10. Therefore, the use of these 25 Y-STR markers may be useful for forensic identification in the Japanese population.
在这项研究中,我们分析了来自 213 对日本父子的 213 份 DNA 样本,这些样本使用了 Yfiler Plus PCR 扩增试剂盒进行了 25 个 Y-染色体短串联重复(Y-STR)(DYS576、DYS389I、DYS635、DYS389II、DYS627、DYS460、DYS458、DYS19、YGATAH4、DYS448、DYS391、DYS456、DYS390、DYS438、DYS392、DYS518、DYS570、DYS437、DYS385、DYS449、DYS393、DYS439、DYS481、DYF387S1 和 DYS533)标记物的分析。我们计算了每个位点的 Y-STR 突变率,以评估 25 个 Y-STR 标记物在使用男性亲属样本进行亲子鉴定和法医鉴定中的功效。六个快速突变的 Y-STR 标记物(DYS576、DYS627、DYS518、DYS570、DYS449 和 DYF387S1)先前被报道具有较高的突变率(>1.0×10),包含在 25 个 Y-STR 标记物中,但我们的研究结果表明,除了 DYS576 和 DYS458 之外,所有 Y-STR 标记物的突变率均低于 1.0×10。因此,在日本人群中,这些 25 个 Y-STR 标记物的使用可能有助于法医鉴定。
