Population genetic data for 21 autosomal STR loci in the Azerbaijani population using the Globalfiler™ kit


The Republic of Azerbaijan is located in the southern Caucasus mountains, a region which is linguistically and ethnically diverse. We report allele frequency data for 21 autosomal loci from the Globalfiler™ kit in the Azerbaijani population using 467 individuals from Baku. Exact tests for Hardy Weinberg Equilibrium and Linkage Equilibrium were conducted, and all forensic parameters were estimated. High levels of Expected Heterozygosity HE were seen, with a minimum of 0.637 for TPOX and a maximum of 0.949 for SE33. Polymorphism Information Content (PIC) values for all STR loci were high, ranging from 0.587 for TPOX to 0.947 for SE33. Matching probability (MP) estimates ranged from 0.006 for SE33 to 0.178 for TPOX. Power of Discrimination (PD) values for most of the tested loci (17/21) were ≥ 0.9. The Combined Matching Probability (CMP) and the Combined Power of Discrimination (CPD) for all 21 loci were 7.84 × 10–27 and 1.0 respectively. Exact tests for population differentiation using all available Globalfiler™ datasets from across Europe and Asia reveal a general trend of higher differentiation with increasing geographical separation, but there is a need for additional population data from neighboring regions of Azerbaijan.
