Drug Resistance Mechanism of M46I-Mutation-Induced Saquinavir Resistance in HIV-1 Protease Using Molecular Dynamics Simulation and Binding Energy Calculation.
Introduction: The study reported by Bastys et al., (2020) studied the effect of M46I and other background mutation(s) on the drug resistance potential of N88S and L76V and primary mutations in HIV-1 protease.
Detection of Gag C-terminal mutations among HIV-1 non-B subtypes in a subset of Cameroonian patients.
Introduction: Following the Stanford algorithm (mutation list), minor resistance mutations (L10F, V11I, K20TV, L23I, L33F, K43T, F53L, Q58E, A71IL, G73STCA, T74P, N83D, and L89V) are assumed to have ancillary roles such as compensation for lower efficiency of proteolysis caused by major mutations; major resistance mutations (V32I, M46IL, I47VA, G48VM, PMID: 34897227

Prevalence and factors associated with HIV-1 drug resistance mutations in treatment-experienced patients in Nairobi, Kenya: A cross-sectional study.
Abstract: N88S and L76V, do not only induce resistance to the currently administered drugs, but contrarily induce sensitivity towards other drugs.
Abstract: Finally, we show that L76V and N88S changes the hydrogen bond stability of these residues with residues D30/K45 and D30/T31/T74, respectively.
Abstract: In this study, mutations N88S and L76V, along with three other resistance-associated mutations, M46I, I50L, and I84V, are analysed by means of molecular dynamics simulations to investigate their role in complexes of the protease with different inhibitors and in different background sequence contexts.

Trend of HIV-1 drug resistance in China: A systematic review and meta-analysis of data accumulated over 17 years (2001-2017).
Abstract: DRMs were common, with 28 of 179 (15.6%) specimens carrying DRMs, including the PR N88S and RT K103N mutations, which have been implicated in elevated resistance to antiretroviral drugs.
Result: The PI major DRMs included M46L, M46I and N88S.

Discussion: M46I/L caused PLLR to many INSTIs among HIV-1 positive individuals, while N88S could result in HLR to Atazanavir (ATV) and NFV, LLR to Indinavir (IDV) and Saquinavir (SQV).
Discussion: Q58E and other DRMs (
