Abstract

The study presents South American mitochondrial DNA (mtDNA) data from selected north (N = 98), central (N = 193) and south (N = 47) Argentinean populations. Sequence analysis of the complete mtDNA control region (CR, 16024–576) resulted in 288 unique haplotypes ignoring C-insertions around positions 16193, 309, and 573; the additional analysis of coding region single nucleotide polymorphisms enabled a fine classification of the described lineages. The Amerindian haplogroups were most frequent in the north and south representing more than 60% of the sequences. A slightly different situation was observed in central Argentina where the Amerindian haplogroups represented less than 50%, and the European contribution was more relevant. Particular clades of the Amerindian subhaplogroups turned out to be nearly region-specific. A minor contribution of African lineages was observed throughout the country. This comprehensive admixture of worldwide mtDNA lineages and the regional specificity of certain clades in the Argentinean population underscore the necessity of carefully selecting regional samples in order to develop a nationwide mtDNA database for forensic and anthropological purposes. The mtDNA sequencing and analysis were performed under EMPOP guidelines in order to attain high quality for the mtDNA database.

Fast mutations were eliminated applying the EMPOPspeedy filter [18]. The size of a node corresponds to the log-value of the number of haplotypes pooled in that node. Nodes include the name of the haplogroup; multiple haplogroups within a node are indicated by the most frequent haplogroup and “+.” Transitions are displayed in green, transversions and indels in red. Upper case letters correspond to the IUPAC code; lower case letters denote a combination of the designation with the upper case letter and a deletion (PDF 12 kb)
