Abstract

The most efficient markers to solve filiation cases are the STRs, including complex cases that require the analysis of a greater number of markers. In this study samples from 123 unrelated individuals from the department of Santander (northeast Colombia) were typed for 23 autosomal STRs included in VeriFiler express kit (Thermo Fisher Scientific),and their allele frequencies and parameters of forensic relevance were determined. Results demonstrate independence within and between the loci analyzed, and the accumulate power of exclusion for the full set of markers was high (99.9996%), as well as the match probability, which was 1 in 8.77E\,+\,29. Therefore, this northeast Colombian population database can be used in forensic to estimate the frequency of the genetic profile using of a multiple locus including in this DNA kit.
