Frequencies of SDF-1 chemokine, CCR-5, and CCR-2 chemokine receptor gene alleles conferring resistance to human immunodeficiency virus type 1 and AIDS in Kuwaitis.

摘要

The frequencies of three mutations conferring resistance to HIV/AIDS were determined in a population sample of native Kuwaitis. The CCR2-641, SDF1-3'A, and CCR5-m303 mutations were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) tests using restriction endonucleases Bsa BI, Msp I, and Hinc II, respectively. The frequency of the mutant alleles were: for CCR2-641, 0.1195 (95% CI 0.0801-0.1694); for SDF1-3'A, 0.2593 (95% CI 0.2024-0.3231), and for CCR5-m303, less than 0.0025. Thus, the CCR2-641 and especially SDF1-3'A mutations are sufficiently common in Arabs and can be used for prognostic genotyping in HIV-infected individuals from the Gulf countries.
