Allele frequencies and population data for 17 Y-STR loci included in the AmpFlSTR® Y-filer™ PCR amplification kit (Applied Biosystems, Foster City, USA), that permit 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 166 healthy unrelated males resident in Casablanca (from Morocco). A total of 166 haplotypes were identified, of which 142 were unique. The overall haplotype diversity for the 17 Y-STR loci reached 0.9974, and a discrimination capacity was 0.855. We report some non-standard situations, including duplications and microvariant alleles.
