Abstract

This study was aimed to establish a database of autosomal Short Tandem Repeat (aSTR) DNA allele frequencies for an Iraqi population living in Baghdad city as a reference, therefore, a total of 456 unrelated individuals were analyzed at 15 STR DNA markers (D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, TH01, TPOX, CSF1PO, D19S433, D2S1338, D16S539) included in the Kit from Applied Biosystems. The obtained results revealed that the Combined Matching Probability (CMP) was estimated at 1 in 3.3287 × 10^-18, and the Combined Discrimination Power (CDP) was greater than 0.98600987, which is comparable to values obtained with the many other allele frequency databases used in forensic investigations. It can be concluded that for identification purposes, it can be considered the multi-locus STR panels as a useful forensic tool.
