Analysis of 15 short tandem repeats reveals significant differences between the Arabian populations from Morocco and Syria.

The short tandem repeat (STR) systems D3S1358, TH01, D21S11, D18S51, Penta E, D5S818, D13S317, D7S820, D16S539, CSF1PO, Penta D, vWA, D8S1179, TPOX and FGA were studied in Arabian population samples from Morocco and Syria. No significant deviation from Hardy-Weinberg equilibrium could be observed in either preparation. Comparing the Moroccan and Syrian populations using the program RxC, no similarity could be observed at all 15 loci. In the Moroccan and Syrian populations the matching probability is 1 in 1.4 x 10(17) and 1 in 2.6 x 10(17), respectively. Thus, the combination of these 15 STR loci is powerful tool for forensic identification in Arabian populations.
