Allele frequencies of fifteen STR loci in a population from Central Brazil.

Allele frequencies for 15 short tandem repeats included in Powerplex 16 Kit (Penta E, D18S51, D21S11, TH01, D3S1358, FGA, TPOX, D8S1179, vWA, Penta D, CSF1PO, D16S539, D7S820, D13S317 and D5S818) were determined in a sample of 429 unrelated individuals from the population of Goiânia, Goias, Central Brazil. Determination of the allele frequencies as well as of several commonly used statistics in forensic and paternity testing were defined. The forensic parameters presented high values and the most polymorphic loci were Penta E, following FGA and D18S51. The exact test demonstrated that the fifteen loci analyzed in the population of Goiania have no deviation from Hardy-Weinberg equilibrium (P > 0.05).
