Method: NNRTI-selected mutations included A98G, L100I, K101E/P/N/H, K103N/S, V106A/M, V108I, V179D/E, Y181C/I/V, Y188L/C/H, G190A/S/E/Q, P225H, F227L, M230L, P236L, and K238T.
Natural polymorphism in protease and reverse transcriptase genes and in vitro antiretroviral drug susceptibilities of non-B HIV-1 strains from treatment-naive patients.
Abstract: Some mutations could be associated with decreased in vitro susceptibility: 1 of 3 strains only with mutations M46I/L in protease, 1/2 A98S, K101N, V108I, V179I, and P236L in reverse transcriptase.
HIV-1 drug-resistance mutations among newly diagnosed patients before scaling-up programmes in Burkina Faso and Cameroon.
Abstract: In Cameroon, resistance mutations were identified in 8 of 102 patients: three to PIs (M461/L [n = 2], L33F [n = 1]), three to NRTIs (T69N/T [n = 1], M184V [n = 1], A62V [n = 1]) and two to NNRTIs (P236L [n = 1], V1081 [n = 1]).

Abstract: Six of 35 (17%) individuals harbored primary mutations for RT inhibitors, including M41L, V118I, Y188H, P236L, and Y318F, and curiously three of the six were infected with CRF06_cpx.
Genetic characterization of human immunodeficiency virus type 1 from Beira, Mozambique.
Abstract: Although an unexpectedly high rate (11.6%) of reverse transcriptase key mutations (V75A, K103N, Y181C, M184I, or P236L) was detected in the sequences analyzed, our data suggest the non-epidemic circulation of resistant viruses, and the absence of multi-class drug resistant viral strains.
HIV-1 reverse transcriptase mutants resistant to nonnucleoside reverse transcriptase inhibitors do not adversely affect DNA synthesis: pre-steady-state and steady-state kinetic studies.

Abstract: In this study, we evaluated the polymerase function of 3 clinically occurring NNRTI-resistant RTs (K103N, P236L, and V106A) in greater detail, under both pre-steady-state and steady-state conditions.

Abstract: An IC(50) of 86 nM was obtained with a mutant virus having V106I, E138K, and P236L mutations that resulted from serial passage of WT virus in the presence of GW678248.
Abstract: In HeLa CD4 MAGI cell culture virus replication assays, GW678248 has an IC(50) of < or =21 nM against HIV-1 isogenic strains with single or double mutations known to be associated with NNRTI resistance, including L100I, K101E, K103N, V106A/I/M, V108I, E138K, Y181C, Y188C, Y188L, G190A/E,

Abstract: Resistant progeny viruses recovered after eight passages had amino acid substitutions V106I, E138K, and P236L in the reverse transcriptase-coding region in one passage series and amino acid substitutions K102E, V106A, and P236L in a second passage series.
