Genetics of Diego blood groups in Guatemalan Indians: use of antiserums to Diego a and Diebo b antigens.
Red blood cells of 255 inhabitants of San Antonio Palopo, an Indian community on the eastern shore of Lake Atitlán, Guatemala, have been typed with antiserum.. to Diego a (Di(a)) and the newly discovered antiserum to Di(b). Individuals with erythrocyte antigenic types Di(a+ b-, Di(a+ b+), and Di(a-b+) have been found, but the type Di(a-b-) has not been encountered. Population frequencies of antigenic types and family studies support the hypothesis that the erythrocyte antigens, Die and Dib, are controlled by two codominant alleles at a single autosomal locus.
