Objective: To evaluate the power of Identifiler System for paternity testing.
Methods: A total of 3 277 paternity testing cases were studied using Identifiler System. The exclusion power and mutation rates of the Identifiler 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 System is powerful and reliable for paternity testing.
