Comparative allele distribution at 16 STR loci between the Andean and coastal population from Peru

Abstract 

In the present study, we analysed the allelic distribution of 16 autosomal short tandem repeats (STRs) performed on unrelated individuals from seven different Peruvian cities, three highland Andean cities and four coastal ones. The loci investigated were F13A01, FESFPS, vWA, CSF1PO, TPOX, TH01, D16S539, D7S820, D13S317, D5S818, D19S253, F13B, D21S11, LPL and D8S1179 y D3S1358. The allele frequency, statistical parameters, Hardy–Weinberg equilibrium and population pair comparison across all loci were determinate. The combined matching probability for the 16 loci was 5.41136×10⁻¹⁵ and the combined probability of exclusion (PE) was 0.999998307. The results showed new local databases for the evaluation of Andean and coastal Peruvian populations in human identity testing.
