The aim of the study was to evaluate the usefulness of the NGM SElect multiplex kit for paternity testing in the population of central Poland, and compare it with the IDENTIFILER system. The study material consisted of buccal swabs taken from individuals who reported to the Medical and Forensic Genetics Laboratory in Lodz. Samples from 450 trio cases of disputed paternity carried out in 2010–2014 were investigated. Genomic DNA was extracted from buccal swabs collected from 1,350 individuals using the Swab kit (A&A Biotechnology) according to the manufacturer’s protocol. DNA amplification was performed using the AmpFℓSTR® NGM SelectTM PCR Amplification Kit (Life Technologies). PCR products were separated by capillary electrophoresis using HID 3500 Genetic Analyzer. In the analyzed cases with paternity confirmation in the NGM SElect system, the maximum value of PI was 3.9 × 1012, which corresponds to the probability of paternity W = 99.9999999999%. It was thus significantly higher than analogical parameters obtained in the IDENTIFILER system (PI = 6.0 × 1010, W = 99.99999999%). The NGM SElect kit was unable to resolve just one case out of 450, which represents only 0.2% of all analyzed disputed paternity cases. The study showed the SE33 (ACTBP2) locus to have the highest evidence value in paternity analysis out of all investigated autosomal STRs.
