    Notes: Serological HLA types (A, B, C, DR and DQ loci) were studied in five different Indian tribes (Cubeo, Tucano, Coreguaje, Embera and Noanama) belonging to two distinct linguistic families. For all the MHC loci, the range of variation among the five tribes was enormous. Two tribes, Cubeo and Tucano, showed a wide spectrum of antigenic specificities which seemed to be due to admixture from non-tribal groups, while in the other three tribes the polymorphisms of various HLA loci showed restricted distributions. The gene frequency data, when converted to a kinship matrix and a two-dimensional eigenvector plot, indicated that members of the same linguistic family tend to have greater genetic affinity.

    HLA-DPB 1 POLYMORPHISM IN SEVEN SOUTH AMERICAN INDIAN TRIBES IN COLOMBIA (1996)

    Notes: HLA-DPB 1 allele frequencies were investigated in seven geographically and linguistically distinct Amerindian tribes of Colombia. Allele *1301 was found only in the Embera tribe living along the Pacific coast, while allele *0101 was found only in two individuals of the Wayuu tribe inhabiting the Guajira desert. Significant geographical variation was observed in the other two alleles (*1401 and *0402), which were found in all seven tribal groups. The possible reasons for this restricted polymorphism and the genetic diversity found in the investigation are discussed.

    Complement C3 polymorphism in sixteen populations of Colombia. Results of “Expedicion humana” (1995)

    Notes: Abstract Blood samples of 1.022 individuals of both sexes, collected during the “Expedicion Humana” programme. Twelve Indian group, two Negroes, two urban and one mestizo populations of Colombia were C3 typed. The results showed the urban samples have C3*F genotype frequencies (17 and 20%) similar to the Spanish population. The Negroe system, with lower C3*F gene frequencies (3.5 and 7%) also resembled their parental populations in Africa. The Mestizo population reported in this study showed a lower value of the C3*F gene (2.2%) than previously studied. suggesting that the degree of admixture may vary in different regions of the country. As regards the Indian populations, there was a wide range of variation of the C3*F gene (0–19%) many tribes being monomorphic. This gene may be a marker of recent admixture in Amerindians, but there may be other genetic factors, such as selection and inbreeding in maintaining high levels of genetic polymorphism in tribes such as Guahibo.

    HLA antigens (A,B,C and D) among two groups of Guahiboan speaking Indians in Colombia. “Results of expedicion humana” (1995)

    Notes: 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.
