HLA antigens (A, B, C and D) among two groups of Guahiboan speaking Indians in Colombia.“Results of expedicion humana”

Abstract:

The serological HLA types (A,B,C and D loci) were studied in the Sikuani and Guayabero, two Guahiboan speaking Indian groups inhabiting the eastern lowlands of Colombia. Besides restricted polymorphism, the results show significant differences only in two antigens, A2 and B35, suggesting genetic similarity among these tribes which belong to the same linguistic family. Genetic distances were calculated for comparison with other Colombian groups so far studied, showing the lowest distance between the two tribes under study. The Guayabero were closer to the urban population of Bogota, which suggests that the genetic structure of the present day Amerindians of South America may be significantly influenced by the European populations.
