Validation of nine non-CODIS STR loci for forensic use in a population from Central Poland.
The D7S1517, D3S1744, D12S391, D2S1360, D6S474, D8S1132, D5S2500, D10S2325 and D4S236613 are STR loci potentially useful for forensic purposes whose analysis has recently become facilitated by availability of a commercial kit. The purpose of the study was to evaluate the usefulness of these loci for forensic identification in a population of Central Poland. The distribution of alleles of the nine STRs was determined in sample of 353 unrelated individuals born in Central Poland and indices of forensic informativeness were calculated. The studied loci were highly informative and did not show departures from Hardy-Weinberg equilibrium. For the loci located on the same chromosomes (D2S1360, D3S1744 D4S2366, D5S2500, D7S1517, D8S1132, D12S391) as other loci commonly used for identification purposes (TPOX, D2S1338, D3S1358, FGA, D5S818, D7S820, D8S1179 and D12S391) appropriate pairwise analysis of linkage disequilibrium was performed. In all cases no statistically significant deviation from independence was found. We conclude that the studied STRs are informative and, when necessary, can be used to extend the results obtained with other STRs commonly analyzed for identification purposes, in particular the CODIS set.
