Y-chromosome STR defined haplotypes in North Portugal

The Y-specific STR loci, DYS19, DYS385, DYS389I and II, DYS390, DYS391, DYS392, DYS393, DYS434, DYS437, DYS438, DYS439 and GATA A10, were studied in the Northern Portuguese population. In a sample of 212 individuals, it was possible to define 196 different haplotypes of which 182 were found only once, 12 were found in two samples and the 2 most frequent haplotypes were shared by three individuals. The observed haplotype diversity value was 0.9992. The usefulness of the inclusion of each of these new markers for forensic purposes is discussed, comparing expected and observed increase in haplotype diversity. D 2003 Elsevier Science B.V.
