Analysis of eight mtDNA coding region polymorphisms for characterization of the female lineages ancestry in Alagoas, Brazil

Abstract In this work we evaluated eight mitochondrial DNA coding region polymorphisms (8281–8289d, 1736, 13263, 4883, 3594, 10873, 10400, and 12705) in order to identify lineages of African, Amerindian and European origin in Alagoas, Northeastern Brazil. Seven of these polymorphisms were detected by multiplex minisequencing with SnaPshot. For validation purposes a sample previously characterized by sequencing of the HVI and HVII regions was analyzed. Good agreement was observed between the phylogenetic results obtained in this work and the HVI and HVII regions sequencing. The results obtained suggest that the set of markers evaluated in this study can be used in ancestry studies of Brazilian populations.
