Human Leucocyte Antigen (HLA) loci are widely known for their role in the generation of immune responses and are often considered to be effective in reconstructing human relationships. This is due to the high degree of polymorphism and the rarity of recombination observed at HLA loci. In this study, we have made an attempt to support the potential of HLA class II loci by analysing DQA1 and DQB1 in 52 Ecuadorians with ties to the Tsachilas community. Little is known about this populations either ethnologically or historically: they are considered retaining much of the ancient Chibchan culture in spite of the lack of significant genetic characterization. A total of 21 alleles were observed, with very low heterozygosity. The obtained data were then assessed for relationship reconstruction. The compiled database of 63 populations was segregated and resolved in clusters corresponding to the ethnogeographic distribution of the populations. This analysis of Central and Southern Amerindians allowed us to support a historical hypothesis related to the origin and migration of Ecuadorian people. Indeed, the relationships with neighbour human groups, especially Cayapas and Colombians, could shed light on the genetic similarity within ancient Chibchan culture that was dispersed by tribes coming up the Barbacoas. This indicates that if an appropriate analysis was to be carried out on a set of populations representative of different geographic locations, and that analysis was properly interpreted, then there would be a high possibility that HLA class II loci could infer accurate assessments, as revealed by uniparental markers.
