摘要
目的 探讨MHSeqTyper47试剂盒在亲缘关系鉴定中的应用价值.方法 采用MHSeqTyper47试剂盒对113份亲缘关系个体DNA样本进行基因座复合扩增及文库构建,使用MiSeq FGx测序仪进行测序,测得的数据应用MHTyper数据分析软件进行基因分型,计算亲缘关系指数评估该试剂盒在亲缘关系鉴定中的应用效能并与GlobalFilerTM试剂盒进行比较.结果 MHSeqTyper47在三联体鉴定中CPI值1.43×1011~6.15× 1018,二联体鉴定中CPI值3.75× 105~1.53×1013,全同胞鉴定中CFSI值7.73× 101~2.59× 1016,三联体、二联体和全同胞关系对均与无关个体对可以完全区分.MHSeqTyper47和GlobalFilerTM试剂盒联用在二级亲缘关系中的系统效能为0.466 2.结论 MHSeqTyper47混合DNA鉴定试剂盒在一级亲缘关系鉴定中有较高的应用价值;与GlobalFilerTM试剂盒联用在二级亲缘关系鉴定中可以解决部分案例.
Abstract
Objective To investigate the application value of the MHSeqTyper47 kit in kinship identification.Methods Multiplexed amplification and library preparation were performed for DNA samples from 113 related individuals by using the MHSeqTyper47 kit.The libraries were sequenced on a MiSeq FGx sequencer,and the data were analyzed using MHTyper for microhaplotype genotyping.The kinship indexes were calculated to evaluate the application efficiency of this kit in kinship identification and compared with those of the GlobalFilerTM kit.Results For the MHSeqTyper47 kit,the CPI values in trio identification were 1.43× 1011~6.15×1018.The CPI values in duo identification were 1.02× 105~1.53× 1013.The CFSI values in full sibling identification were 7.73×101~2.59×1016.Trios,duos and full siblings could be completely distinguished from unrelated pairs.The combined efficiency of these two kits in 2nd-degree kinship identification was 0.466 2.Conclusion The application value of MHSeqTyper47 kit is relatively higher in the identification of lst-degree kinships.If jointly used with the GlobalFilerrM kit,2nd-degree kinship identification could be achieved in some cases.
