The AmpFlSTRR Identifilerk is a multiplex kit which coamplifies 16 STR loci, including the segment of the X-Y homologus gene Amelogenin. The study of these STR loci is important for the formation of local human identification databases in order to statistically evaluate the evidence. This report presents allele frequency data for 15 STR loci in 150 unrelated individuals from Bahia, Brazil. The genotype frequencies of the 15 STR loci showed no deviations from HWE expectations. The combined power of exclusion is estimated as 99.99996% and the combined power of discrimination is 99.9999999999999999%. D 2003 Elsevier B.V. All rights reserved.
