X-chromosome genetic variation in São Paulo State (Brazil) population.
As data on X-chromosomal short tandem repeats (X-STRs) for the Brazilian population are scarse, the aim of this study was to determine the allele frequencies of five X-STRs (DXS6854, DXS7424, DXS101, DXS6808 and DXS7132) in the São Paulo State, Brazil. No deviations from the Hardy-Weinberg equilibrium were observed, with the exception of DXS101. The forensic efficiency parameters demonstrated that DXS101 was the most informative marker. Population comparisons revealed that the X-STR profile sampled in the state of São Paulo was more similar to European and African populations than Asiatic populations reported in this work.
