The frequency distribution of the CCR5-delta32, CCR2-64I, and SDF1-3'A alleles was studied in the urban population of Belem and in Afro-Brazilians, Amerindians, and Japanese immigrants in the state of Para, Brazil. The results suggest that Amerindians may be genetically more susceptible to HIV-1 infection and disease progression than the other human groups studied. |
