Identifiler^(TM)系统在亲子鉴定中的应用评估

The Evaluation of Identifiler^(TM) System in Paternity Testing

目的评估IdentifilerTM系统15个短串联重复序列(STR)基因座在亲子鉴定中的检验能力。方法用IdentifilerTM系统检测3277例亲子鉴定案例,观测和分析该系统在亲子鉴定中的排除能力及基因突变率。结果累积非父排除率为0.999998827,累积个体识别能力为0.99999999999999998。3277例亲子鉴定中有2863例认定亲权关系,347例排除亲权关系;观察到65例中有1个STR基因座发生突变,2例中有2个STR基因座发生突变。结论IdentifilerTM体系应用于亲子鉴定是高效、可靠的。

Objective To evaluate the power of Identifiler^TM System for paternity testing. Methods A total of 3 277 paternity testing cases were studied using Identifiler^TM System. The exclusion power and mutation rates of the IdentifilerTM System were analysed in the paternity testing. Results The cumulated power of exclusion was 0.999 998 827, and the cumulated discriminating power was 0.999 999 999 999 999 98, respectively. Of the 3 277 cases, paternity was confirmed in 2 863, but excluded in 347. Among this paternity testing, mutations involving a single STR locus were observed in 65 cases, while mutations involving 2 STR loci were observed in 2 cases. Conclusion The Identifiler^TM System is powerful and reliable for paternity testing.
