Studies on P-glycoprotein expression and function have revealed that a single nucleotide polymorphism (SNP) in the human ABCB1 gene at 3435 (C > T) results in altered expression and function of P-glycoprotein [1, 2].There have been reports of lower nelfinavir and efavirenz (EFV) concentrations associated with TT genotypes (mutant) of ABCB1 C3435T polymorphism [3, 4].Frequency distribution of this polymorphism is known to vary across populations [3, 5, 6]. We report the genotype distribution of ABCB1 C3435T in 179 individuals (126 HIV-infected and 53 healthy) from South India. The polymorphism was correlated with plasma 12 h EFV and 2 h nevirapine (NVP) concentrations in 55 and 71 patients, respectively. Plasma EFV and NVP were estimated by HPLC [7, 8]. Genotyping was carried out by PCR-RFLP [9].
