Haptoglobin and Transferrin Types in Peruvian Indians

RECENT reports on the incidence of the serum haptoglobin types of American Indians have included observations on natives of Alaska1, south-western United States2,3, southern Mexico and Guatemala4, Venezuela5, and Chile3. The incidence of the Hp1 gene, shown in Table 1, is usually higher than that found in the population of western Europe4 (gene frequency 0.32–0.43, mean about 0.39). In several tribes, the occurrence of Hp1 is as frequent as that reported in the various Bantus of Africa4 (0.49–0.87). This finding is of particular interest when compared with the low incidence of Hp1 (0.09–0.28) in Asiatic populations2,6. Since genetic drift is often responsible for marked fluctuations in the concentration of given genes in comparatively isolated areas, more observations are necessary to confirm these apparent differences. We have investigated the haptoglobin (and transferrin) types of two Peruvian Indian groups.
