Validation of five X-chromosomal STRs DXS6800,DXS6807, DXS6798, DXS8377 and DXS7423 in anAntioquian population sample

摘要

The X linked short tandem repeat (STR) markers have proven to be very useful tools for paternity testing when the disputed child is female This paper aims to describe the polymorphism of five X-chromosomal STR loci (DXS6800, DXS6807, DXS6798, DXS8377 and DXS7423) in an Antioquian (Colombian) population sample, and evaluate their efficiency in forensic practice and paternity testing. The comparisons of the allele frequency distributions for Antioquian population are similar to European populations. The forensic efficiency values demonstrate that especially DXS8377 and DXS6798 are highly informative markers for kinship analysis and deficiency cases.
