15 STR loci frequencies with mutation rates in the population from Rio Grande do Sul, Southern Brazil

Allele frequencies for 15 short tandem repeats (STR) loci were obtained from a sample of 2038 individuals undergoing paternity testing. The population is from Rio Grande do Sul, Brazil. The loci are the most commonly used in forensic and paternity testing, being analysed by the AmpFlSTR® Identifiler (Applied Biosystems) commercial kit. The most polymorphic locus was D2S1338. Mutation rates were ascertained from this population sample. All the loci analysed reached the Hardy–Weinberg equilibrium. The results of genetic distance are consistent with the European-derived origins of Rio Grande do Sul population.
