Trends of Transmitted and Acquired Drug Resistance in Europe From 1981 to 2019: A Comparison Between the Populations of Late Presenters and Non-late Presenters.
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

Rising rates of recent preexposure prophylaxis exposure among men having sex with men newly diagnosed with HIV: antiviral resistance patterns and treatment outcomes.
Abstract: The predominant DRMs for non-nucleoside reverse transcriptase inhibitors (NNRTIs) and nucleoside reverse transcriptase inhibitors (NRTIs) were V179D/E/A/DIN (13.60%) and M184V/I (1.44%), respectively, whereas only two major DRMs (M46L and I54L) were identified for protease inhibitors (PIs).
Acquired HIV-1 Protease Conformational Flexibility Associated with Lopinavir Failure May Shape the Outcome of Darunavir Therapy after Antiretroviral Therapy Switch.
Introduction: The major HIV-1 PI resistance mutations that affect the efficacy of boosted LPV regimen are V32I, L33F, M46I/L, I47V/A, I50V, I54V/T/A/L/M, L76V, V82A/F/T/S, I84V.
Temporal Trends in HIV-1 Mutations Used for the Surveillance of Transmitted Drug Resistance.
Result: The PI-SDRMs with the lowest treatment/naive prevalence ratios were F53Y (5-fold), V82L (7-fold), M46L (9-fold), and I85V (14-fold).
Discussion: Four PI-SDRMs (M46L, F53Y, V82L, and I85V) had relatively low treated/naive prevalence ratios.
Discussion: The potential for M46I/L to occur at low levels in subtype A and CRF01_AE populations without previous PI exposure was recognized at the time the 2009 SDRM list was developed and in several subsequent analyses.
Transmitted HIV-1 drug resistance in a large international cohort using next-generation sequencing: results from the Strategic Timing of Antiretroviral Treatment (START) study.
Abstract: Using the 2% detection threshold, individual DRMs with the highest prevalence were: PI M46IL (5.5%), RT K103NS (3.5%), RT G190ASE (3.1%), T215ISCDVEN (2.5%), RT M41L (2.2%), RT K219QENR (1.7%) and PI D30N (1.6%).
Discussion: study, a similar pattern was observed, with the M46IL and D30N detected predominately as minor variants while the majority of
