Abstract: In the RT gene, three major mutations were detected in six strains: the V75M mutation in one strain, the Y181C mutation in two strains, and the M184I mutation in three strains.
Virologic failures on initial boosted-PI regimen infrequently possess low-level variants with major PI resistance mutations by ultra-deep sequencing.
Abstract: The most common UDS-detected DRM were NRTI in 18 subjects: M184V/I (11), TAMs(7) & K65R(4); PI DRMs were detected in 9 subjects: M46I/V(5), F53L(2), I50V(1), D30N(1), and N88S(1).
Discussion: Eleven of 24 patients had low or high level M184V/I variants; 7 had M184V/I at >=1% of the viral population, however only 4 of the 7 developed phenotypic resistance to FTC/3TC (all had M184V variant levels >95%).
Discussion: Interestingly, not all patients with M184V/I developed phenotypic resistance to F
HIV-1 subtype D infections among Caucasians from Northwestern Poland--phylogenetic and clinical analysis.
Introduction: Consistent with this observation, mechanistic analyses suggest that this mutation may compensate for the antagonism of TAMs by M184V/I and Y181C.
Introduction: For example, Yap et al reported that the N348I mutation is highly associated with TAMs, the lamivudine mutation M184V/I, and the non-nucleoside inhibitor resistance mutations K103N and Y181C/I.

Abstract: OBJECTIVES: To compare the frequency of the selection of the M184V/I resistance mutation in HIV-infected patients who experienced virological failure while receiving emtricitabine (FTC) or lamivudine (3TC), administered with tenofovir disoproxil fumarate (TDF) and either efavirenz (EFV) or a ritonavir-boosted protease inhibitor (PI; lopinavir or atazanavir).
Abstract: Proportions of patients harbouring the M184V/I mutation were 24% (n = 62) for those who received FTC + TDF + EFV versus 51% (n = 91) for 3TC + TDF + EFV (P < 0.0001; Fisher's exact test); proportions were 11% (n = 30) for FTC + TDF + ritonavir-boosted PI versus 22% (n = 37) for 3TC + TDF + ritonavir-boosted PI (P = 0.002; Fisher's exact test).
Low prevalence of transmitted drug resistance in patients newly diagnosed with HIV-1 infection in Sweden 2003-2010.
Abstract: SDRMs were identified in 14/219 (6.4%) subjects; 8/14 were resistant to nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs; T69D, L74V, V75M, M184V/I and K219R), 5/14 to non-nucleoside reverse transcriptase inhibitors (NNRTIs; K103N, V106M, Y181C, Y188C and G190A), 1/14 to both NRTIs and NNRTIs (D67N and Y181C) and none to PMID: 22585715

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
Prevalence of Drug Resistance and Associated Mutations in a Population of HIV-1(+) Puerto Ricans: 2006-2010.
Discussion: This is consistent with reports based on large-scale HIV-1 genotypic analyses that identify M184V/I as the most prevalent nucleoside and nucleotide-analog-RT-inhibitor- (NRTI-) resistance mutations that overcome the effects of drugs like emtricitabine and lamivudine.
