ABSTRACT
The Lamas Amerindians are the Chancas descents who established before 1532 a.d. (Spanish conquest) at Lamas City, Wayku quarter in a Peruvian-Amazonian province (San Martin). The Lamas HLA profile shows significant differences with other Amerindians HLA profile, i.e. (a) a higher number of newly found haplotypes compared to other studied Amerindian populations, particularly HLA-A*02-B*48-DRB1*0403-DQB1*0302, A*02-B*48-DRB1*0804-DQB1*0402 and A*02-B*40-DRB1*0407-DQB1*0302; (b) a relative high frequency of HLA-DRB1*0901 (a high frequency southern Asian allele) and HLA-B*48 (a Na-Dene, Siberian and Eskimo allele); both alleles are also found frequently in Quechuas and Aymaras, but not in many other (particularly Meso American) Amerindians and (c) correspondence and neighbor-joining dendrogram analyses show that Lamas (Chancas) may have an origin close to Amazonian Indians that later reached the Andean altiplano.
