CCRL2 and AIDS: When the analysis was restricted to individuals not carrying CCR5-Δ32 (n = 539), the association of CCRL2-167F with AIDS remained significant (RH = 1.69, 95% CI 1.20–2.38), indicating that the CCRL2-167F association is independent of CCR5-Δ32 and not due to its linkage disequilibrium with the latter.
