Result: In our study, other NRTI-RAMs known to be associated with Q151M-mediated multi-nucleoside resistance including A62V, V75I, F77L, and F116Y, were also significantly more common in patients harboring the Q151M mutation (p<0.001).

Method: Sequences were analyzed to identify mutations associated with reduced susceptibility to protease and RT inhibitors, as reported by the International AIDS Society-USA in 2010: RT-M41L, A62V, K65R, D67N, 69 insert, K70R, L74V,V75I, F77L, L100I, K101P, K103N, V106A, V106M, V108I, Y115F, F116Y,
From the chemistry of epoxy-sugar nucleosides to the discovery of anti-HIV agent 4'-ethynylstavudine-Festinavir.
Introduction: The K65R mutation confers resistance to tenofovir and some NRTIs and, the Q151M complex (A62V, V75I, F77L, F116Y, and Q151M) confers resistance to most of the clinically approved NRTIs.

Abstract: In this study we tested EFdA-triphosphate (TP) together with a related compound, ENdA-TP (4'-ethynyl-2-amino-2'-deoxdyadenosine triphosphate) against HIV-1 RTs that carry clinically relevant drug resistance mutations: N348I, D67N/K70R/L210Q/T215F, D67N/K70R/L210Q/T215F/N348I, and A62V/V5I/F77L/F116Y/Q151M.
Introduction: In this study we determine the ability of TDRTIs to block reverse transcription
Low prevalence of transmitted drug resistance in patients newly diagnosed with HIV-1 infection in Sweden 2003-2010.
Method: The following resistance mutations were scored: to nucleoside reverse transcriptase inhibitors (NRTIs): M41L, K65R, D67N/G/E, T69D/insertion, K70R/E, L74V/I, V75M/T/A/S, F77L, Y115F, F116Y, Q151M, M184V/I, L210W, T215Y/F/I/S/C/D/V/E, K219Q/EN/R; to non-nucleoside revers

4Method: ARV resistance was defined by mutations at the following positions: M41L, A62V, K65R, D67N, T69ins, K70R, L74VI, Y115F, F116Y, Q151M, M184VI, T210W, T215YF and K219QE for Nucleoside Reverse Transcriptase Inhibitors (NRTI), L100I, K101EP, K103NS, V106AM
Biochemical, inhibition and inhibitor resistance studies of xenotropic murine leukemia virus-related virus reverse transcriptase.
Discussion: In HIV, decreased binding of AZT is conferred initially in the presence of the primary Q151M mutation, followed by secondary mutations F77L, A62V, V75I and F116Y.
Differential in vitro kinetics of drug resistance mutation acquisition in HIV-1 RT of subtypes B and C.
Discussion: Q151M is a primary mutation that in vivo can be co-selected together with a group of secondary mutations (A62V, V75I, F77L and F116Y) that confers a cross-resistance with all NRTIs.
"K70Q adds high-level tenofovir resistance to ""Q151M complex"" HIV reverse transcriptase through the enhanced discrimination mechanism."
1Abstract: HIV-1 carrying the ""Q151M complex"" reverse transcriptase (RT) mutations (A62V/V75I/F77L/F116Y/Q151M, or Q151Mc) is resistant to many FDA-approved nucleoside RT inhibitors (NRTIs), but has been considered susceptible to tenofovir disoproxil fumarate (TFV-DF or TDF)."
Introduction: This RT contains the Q151M mutation together with a cluster of four additional mutations (A62V/V75I/F77L/F116Y).
The evolution of HIV-1 reverse transcriptase in route to acquisition of Q151M multi-drug resistance is complex and involves mutations in multiple domains.
Introduction: The Q151M MDR complex is composed of the Q151M mutation, which is normally the first to appear, followed by at least two of the following four mutations: A62V, V75I, F77L and F116Y.
