Genetic analysis of 13 STR loci in the population from the State of Pernambuco, northeast Brazil

Allele frequencies for 13 short tandem repeats (STR) loci obtained from a sample of 546 unrelated individuals from the State of Pernambuco, northeast Brazil, were studied. This population represents a trihybrid population composed of individuals presenting an admixture of Caucasian, African, and Nat...

Zusammenfassung:Allele frequencies for 13 short tandem repeats (STR) loci obtained from a sample of 546 unrelated individuals from the State of Pernambuco, northeast Brazil, were studied. This population represents a trihybrid population composed of individuals presenting an admixture of Caucasian, African, and Native American. In the present study, the distributions of the genotypes in the evaluated loci CSF1PO, TH01, TPOX, F13A1, FESFPS, vWA, D16S539, D7S820, D13S317, D18S51, D21S11, D8S1179, FGA are in Hardy–Weinberg equilibrium. These loci were studied together with the Amel locus to perform the CODIS systems used in the USA. The calculated forensic parameters showed that the loci are useful for the solution of forensic problems in the Brazilian northeast region.
