Abstract

A polymorphism,—179G/T, in the promoter of the interferon (IFN)-γ gene (IFNG) confers differential tumor necrosis factor-α (TNF-α) inducibility to the IFNG =romoter. The rarer allele, −179T, but not −179G, is inducible by TNF-α.We investigated the effects of IFNG −179G/T on AIDS pathogenesis. In 298 African American human immunodeficiency virus (HIV)-1 seroconverters, the IFNG −179G/T genotype was associated with accelerated progression to CD4<200 and AIDS-1993, a finding suggesting that IFNG −179T is a risk factor for AIDS progression, as measured by CD4 cell count. It is possible that increased IFN-γ production induced by TNF-α when −179T is present causes CD4 cell depletion by apoptosis.
