Allele Frequency of 15 Autosomal Short Tandem Repeat Loci in Iranian Population with Comparison to Some Other Population

Background: Short tandem repeat (STR) markers are extensively being used forhumanidentification as well as paternity and forensicanalysis of biological evidence.Objectives: The aim of this study was to investigate the allelic frequencies and several forensic and paternity parameters of 15 autosomalshort tandem repeat (STR) loci D3S1358, D16S5391, D7S820, D8S1179, D21S11, D18S51, D5S818, D13S317, FGA, THO1, TPOX, CSF1PO,vWA , D2S1338, and D19S433 in the Iranian population.Methods: Estimation of allelic frequencies and several forensic and paternity parameters of 15 STR loci were performed with theAmpFLSTR Identifilerr kit (Applied Biosystems) for 274 unrelated individuals living in Iran.Results: No deviation from Hardy-Weinberg equilibrium was found in any loci studied in this population. Among the 15 STR locianalyzed in the Iranian sample, the most discriminating loci were D21S11, D2S1338, D19S433, D18S51 and FGA with the highest powerof discrimination. The allelic distribution also was compared to 13 other populations including 3 Iranian population living in Syria,Dubai, the USA and in Fars province and 8 population from published studies of Azerbaijan, Bolu in Turkey, Morocco, Syria, Iraq,Saudi Arabia, Turkey, East Anatolia, and Pakistan.Conclusions: It was concluded that the population of present study had the least similarity with Azerbyjani (11 loci) and most similaritywith the Iranian population in USA (15 loci).
