Heterozygosity for a deletion in the CKR-5 gene leads to prolonged AIDS-free survival and slower CD4 T-cell decline in a cohort of HIV-seropositive individuals.
OBJECTIVE: Recently, it has been shown that a homozygous 32 base-pair deletion in the gene encoding CKR-5, a major coreceptor for HIV-1, leads to resistance to infection with HIV-1. We have investigated whether HIV-seropositive individuals who were heterozygous for the CKR-5 deletion had a different course of the disease. DESIGN: Thirty-five high-risk HIV-seronegative and 99 HIV-seropositive Danish homosexual men followed form 1985 to 1996 and 37 blood donors were analysed for their CKR-5 gen...Expand abstract
