Associations of Chemokine Receptor Polymorphisms With HIV-1 Mother-to-Child Transmission in Sub-Saharan Africa: Possible Modulation of Genetic Effects by Antiretrovirals

Abstract

CCR5 promoter, CCR2, and CX3CR1 polymorphisms were associated with risk of MTCT likely through their role as an HIV-1 coreceptor or by modulating the early immune response. Host genetics may continue to alter MTCT when short-course interventions that only partially suppress virus are used. These findings will need to be confirmed in validation cohorts with a large number of infected infants.
