Introduction: In addition, AZT and d4T may also select for the more rarely observed Q151M nucleoside analog mutational (NAM) pathway (Q151M, A62V, V75I, F77L and F116Y), which confers broad-spectra NRTI resistance.
Introduction: The K65R pathway may be associated with the NAM pathway, which is associated with the Q151M, A62V, V75I, F77L and F116Y mutations.

Abstract: EFdA retains potency toward many HIV-1 resistant strains, including the multi-drug resistant clone HIV-1A62V/V75I/F77L/F116Y/Q151M.
Prevalence, genotypic associations and phenotypic characterization of K65R, L74V and other HIV-1 RT resistance mutations in a commercial database.
Abstract: Other NAMs commonly associated with K65R were A62V, S68G and Y115F; their NRTI susceptibilities were similar to those of viruses containing K65R alone.

Abstract: In another subject, the reverse transcriptase A62V mutation was also found in CVL-RNA but not PBMCs.

Abstract: CONCLUSIONS: A62V and S68G serve as partial compensatory mutations for the K65R mutation in reverse transcriptase by improving the viral replication capacity, which is likely due to increased incorporation efficiency of the natural substrates.
Abstract: In clinical isolates, K65R is frequently accompanied by the A62V and S68G reverse transcriptase mutations.
Abstract: METHODS: The role of A62V and S68G in combination with K65R was investigated using phenotypic, viral growth competition, pre-steady-state kinetic, and excision analyses.

Abstract: As majority of treatment-naive cases (89%) in this study were with HIV-1 subtypes A or AE, we excluded A62V mutation and estimated RAMs prevalence in group of treatment-naive HIV-infected individuals as 7%.
Abstract: By many authors A62V is supposed to be a result of polymorphism in RT gene and is excluded from the list of resistance mutations.
Abstract: High prevalence of A62V is typical for HIV-1 subtype A.
Abstract: In most cases it was NRTI mutation A62V that is associated with multinucleoside resistance caused by Q151M, its effect in the absence of Q151M is not known.

Abstract: Amongst the IDU-A strains, there were genotypes containing characteristic secondary drug resistance mutations in the pol gene of V771 and A62V, as well as variants of the wild type.
Mutational patterns associated with the 69 insertion complex in multi-drug-resistant HIV-1 reverse transcriptase that confer increased excision activity and high-level resistance to zidovudine.
Abstract: Further studies, using recombinant RTs obtained by site-directed mutagenesis, revealed that M41L, A62V and in a lesser extent K70R, were the key mutations that together with T69S, T215Y and the dipeptide insertion conferred high levels of ATP-dependent phosphorolytic activity on AZT and d4T-terminated primers.
Abstract: Structural analysis of the location of the implicated amino acid substitutions revealed a coordinated effect of M41L and A62V on the positioning of the beta3-beta4 hairpin loop, which plays a key role in the resistance mechanism.
HIV-1 subtype B protease and reverse transcriptase amino acid covariation.
Abstract: Some protease (PR) drug-resistant mutations were found in these samples, such as D30N (2.27%), D30G (2.27%), M46I (4.55%), M46N (2.27%), I47V (4.55%), I84V (4.55%), I84L (2.27%), N88S (2.27%) and L90S (2.27%) that all belonged to major drug-resistant but A71T (29.55%) belonged to minor resistance mutations Five treated patients were detected having mutations associated RT drug resistance: M41L (5.26%), A62V (5.26%),D67N (5.26%),
