Genetic analysis of the 16 STR loci for human identification in Native Amazonian populations from Perù.

Nowadays, human autosomal STRs are widely used for human identification and resolving the forensic cases. Because of Andean mountains in the west and Amazonian Basin in the east, indigenous inhabitants of Peruvian Amazonian region have been considered among the most isolated human groups of the world. Here, we report genetic profiles (16 autosomal STRs) belonging to 142 individuals from Peruvian Amazonian region. We compared indigenous STR data set to other populations from America, Asia and Europe in order to increase the knowledge about autosomal genetic pool of this population and also improve the comprehension of the demic flows in this area. Our preliminary results show a low number of allelic variants and therefore a low variability among these Amazonian communities. Moreover, the relative high frequencies of some private alleles confirm their belonging to native American groups. In conclusion, the genotyping of these indigenous populations allowed us to provide a more accurate description of Amazonian autosomal genetic landscape, further proposing human identification STRs as a useful tool to human migration study.
