Population data for 21 STRs for the Salvadoran population using GlobalFiler Express and GlobalFiler STR Amplification Kits

With the advent of expanded STR (short tandem repeats) typing kits, it was necessary to determine allele frequencies and other appropriate population data parameters for El Salvador. Samples were collected from the central, east, and west regions of the country and typed for 21 forensically relevant STR loci. The data indicate that all loci are highly polymorphic, the three regions are genetically similar, and the population data are similar to those of US Hispanics. The results of this study support that the allele frequency data described herein can be used for statistical calculations for human identity testing in El Salvador.
