Allele frequency data of 21 autosomal short tandem repeat loci in Mesan and Basra provinces in South Iraq

Abstract

Abstract: We focused on a sample of 100 unrelated persons from the provinces of southern Iraq. This is an analysis of the allele frequency and genotyping of those STR loci in an Iraqi population and this is the first study of its kind in Iraq. As such the data available could be utilized in the Iraqi database for the STR polymorphic markers. Chelex® kit was utilized to extract DNA then Power Plex21® kit (D3S1358, D13S317, PentaE, D16S539, D18S51, D2S1338, CSF1PO, Penta D, THO1, vWA, D21S11, D7S820, TPOX, D8S1179, FGA, D2S1338, D5S818, D6S1043, D12S391, D19S433) was used to amplify the isolated DNA. The mean PIC values and heterozygosity observed across 21 loci were 0.713 and 0.696, respectively. This shows high gene diversity. Those loci can be safely used to establish a DNA-based database for the Iraqi population because the power of discrimination values for all tested loci was from 71% to 97%.
