Allelic frequencies of the 15 STR loci included in the AmpFlSTR® Identifiler™ PCR Amplification Kit in an autochthonous sample from Spain

The aim of this study was to estimate the allelic frequencies of the 15 STR loci included in the AmpFlSTR® Identifiler™ PCR Amplification Kit in a sample of 342 unrelated Caucasian individuals autochthonous from Spain to be used for forensic purposes and population studies. The combined power of discrimination and the combined power of exclusion for all of the 15 loci were 5.68 × 10−18 and 0.9999964, respectively. According to the obtained data, the D18S51 locus may be considered the most informative among the tested loci.
