Introduction: In vitro selection experiments indicated that substitutions in the 74 position combined with major mutations (G140A/C/S, Q148 H/K/R) and other accessory mutations (V75I, T97A) can significantly reduce susceptibility to INSTI, whereas this mutation alone has minimal impact on INSTI susceptibility or HIV-1 replication capacity.

A viral genome wide association study and genotypic resistance testing in patients failing first line antiretroviral therapy in the first large countrywide Ethiopian HIV cohort.
Result: Data regarding accessory mutations to Q151M were available in 155 (86%) patients: A62V was present in 49 (32%), V75I in 62 (40%), F77L in 47 (30%) and F116Y in 99 (64%), and 75% of patients showed at least one accessory mutation.

Characterization of minority HIV-1 drug resistant variants in the United Kingdom following the verification of a deep sequencing-based HIV-1 genotyping and tropism assay.
Result: Most of the minority mutations in viruses from both groups of naive patients were observed in the RT, e.g., M41L, E44D, A62V, K65R, D67N, D67G, V75I, L100I, K103N, K103R, V188I, M184I, L210W, K219Q, Y318F, etc., although a number of minority mutations associated with resistance to PI (L10F, V11I, M46I/

Introduction: However, in the 31 patients with no K65R present at S2, 6 had intermediate or high-level resistance to AZT: 4 were caused by TAM-2 DRMs, 1 by T215Y, and 1 by Q151M-complex mutations Q151M, A62V, V75I, F77L, F116Y.
Transcriptional inaccuracy threshold attenuates differences in RNA-dependent DNA synthesis fidelity between retroviral reverse transcriptases.
Result: Error rates of 3.3 x 10-5 were estimated for the O_K65R/V75I RT under those conditions (Table 4).
Result: In previous studies, we found that the mutant O_K65R/V75I RT was >15-fold more accurate than the HIV-1BH10 RT in forward mutation assays measuring fidelity of DNA-dependent DNA synthesis.
Result: Interestingly, the analysis of mutational spectra revealed that major hotspots obtained with O_K65R/V75I RT while reverse transcribing an RNA template synthesized at pH 7.9/6 mM Mg2.
Result: Interestingly, the spectrum of the O_K65R/V75I RT sh
The HIV-1 Reverse Transcriptase A62V Mutation Influences Replication Fidelity and Viral Fitness in the Context of Multi-Drug-Resistant Mutations.
Abstract: In particular, A62V was observed in various multi-dideoxynucleoside resistant (MDR) mutation complexes, including the Q151M complex (i.e., A62V, V75I, F77L, F116Y, and Q151M), and the T69SSS insertion complex, which has a serine-serine insertion between amino acid positions 69 and 70 (i.e., M41L, A62V, T69SSS, K70R, and T215Y).
Introduction: In particular, A62V is normally seen in different mutational arrangements, located mostly on the flexible beta3-beta4 loop region of the fingers sub-domain of
