Allele frequency data for 17 short tandem repeats in a Czech population sample

Allele frequencies for 17 short tandem repeats (STRs) autosomal loci (D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, CSF1PO, FGA, PentaD, PentaE, TH01, TPOX, vWA) were studied in an extensive sample (max. N=1411) of unrelated individuals originating from the Czech Republic. Population and forensic parameters were estimated. Except for FGA and Penta E loci, no deviations from the Hardy-Weinberg equilibrium were detected. A comparative analysis with published data revealed significant differences in allele frequencies for some loci from the Polish population and three Hungarian populations (Ashkenazim population and Romany populations from Debrecen and Baranya County, respectively). A combination of these 17 STR loci provides a powerful tool for forensic identification in the native Czech population.
