Population data on 6 short tandem repeat loci in a sample of Caucasian-Mestizos from Colombia.

Blood samples from 409-452 unrelated Colombian Caucasian-Mestizo individuals were amplified and typed for six short tandem repeat (STR) markers (HUMF13A01, HUMFES/FPS, HUMVWA, HUMCSF1PO, HUMTPOX, HUMTH01). The allele frequencies, genotype frequencies, heterozygosity, mean paternity exclusion chance, polymorphism information content, discrimination power, assumption of independence within and between loci and Hardy Weinberg equilibrium were determined. The results demonstrate that all markers conform to Hardy-Weinberg equilibrium expectations. In addition, the results demonstrate the assumption of independence within and between the loci analysed. The mean exclusion chance (MEC) was 0.9851 for all six STR loci analysed and the discrimination power (DP) was 0.9999973. Therefore, this Colombian population database can be used in identity testing to estimate the frequency of a multiple PCR-based locus DNA profile in forensic cases as well as in paternity testing.
