Distribution of Y-chromosomal haplotypes in the Central Portuguese population using 17-STRs.

17 Y-chromosome STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS456, DYS391, DYS392, DYS393, DYS385 a/b, DYS458, DYS439, DYS635, GATA H4.1, DYS437, DYS438 and DYS448) were determined for 303 unrelated males, living in Central Portugal, using the AmpFlSTR YFiler PCR Amplification kit (Applied Biosystems). A total of 287 different haplotypes were found, 272 being unique. The overall haplotype diversity (HD) was determined as 0.9996, a value similar to other YFiler data sets. Y-STR polymorphisms in Central Portugal population, using YFiler, provide a powerful discrimination tool for routine forensic applications.
