17 Y-STR haplotype diversity in São Paulo state (southeast of Brazil).

A sample of 158 Brazilian males from São Paulo (SP), Brazilian southeast, was typed for 17 Y-STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, YGATA_H4.1, and DYS385ab). A total of 158 haplotypes were identified, of which all were unique. The haplotype diversity and discrimination capacity were calculated in 1.0 and the genetic diversity was 67.4%. Pairwise haplotype distances showed that the São Paulo population is not significantly different from Rio de Janeiro and Portugal, but is different from African and Native American.
