Abstract: Interestingly, in atazanavir complexes, in the presence of the L76V substitution, the drug revealed a more productive binding affinity, in agreement with hypersusceptibility data.

Abstract: Darunavir resistance-associated mutations have been defined as V11I, V32I, L33F, I47V, I50V, I54L/M, G73S, L76V, I84V, and L89V.

Abstract: The I437T/V mutation in gag and the L76V mutation in the protease were associated with a lower risk of selecting darunavir resistance mutations.
Abstract: There was an association between the presence of the mutation A431V in the gag sequence and the selection of the L76V mutation in the protease sequence in the latest available rebound.
Abstract: Virus with L76V in protease or I437T/V in gag may be already resistant to darunavir and, therefore, no additional resistance mutations need to be selected.
Drug Resistance Mutation L76V Alters Nonpolar Interactions at the Flap-Core Interface of HIV-1 Protease.
Abstract: Besides I47A, mutation L76V at the HIV protease gene has recently been proposed to cause lopinavir resistance.
Abstract: Therefore, L76V does not appear to be a primary lopinavir resistance change when the drug is used in combination therapy.

Abstract: By contrast, L76V, a known DRV resistance mutation, was found to decrease the risk of selection of another DRV resistance mutation.

Abstract: The prevalence of major darunavir resistance mutations was I50V 2.1%, I54M 1.3%, L76V 2.7% and I84V 14.5%.
HIV-1 subtype B protease and reverse transcriptase amino acid covariation.
Figure: Includes the 22 mutations obtained from the mutation pairs with the highest positive association (Table 1) in bold, and 13 additional clinically relevant protease inhibitor resistance mutations (L10F, V32I, L33F, I47V, I50V/L, F53L, I54L/M, Q58E, L76V, V82T, and N88S).
Discussion: Protease covariation was dominated by the clustering of nelfinavir-associated mutations (D30N and N88D), two main groups of PI-resistance mutations
