Abstract

Allele frequencies and population data for 17 Y-STR loci included in a new commercial kit that has recently been available, the AmpFlSTR Y-filer PCR amplification kit (Applied Biosystems), that permits the simultaneous amplification of all the markers included in the actually used European "extended haplotype", DYS19, DYS189I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385I/II, DYS438, DYS439 and also DYS437, DYS448, DYS456, DYS458, DYS635 and Y GATA H4, were obtained from a sample of 175 healthy unrelated males and 45 father-son pairs from the North of Portugal. A total of 171 haplotypes were identified, of which 167 were unique and 4 were found in 2 individuals. The haplotype diversity (99.97%) and discrimination capacity (95.43%) were calculated. We report some non-standard situations, such as allele duplications and mutations. We also report a case of disputed paternity in which duplicated alleles plus an inconsistency of the transmitted alleles appeared.
