Abstract: Of the mutations with the greatest effect on PI susceptibility, I84AV was associated with decreased susceptibility to eight PIs; V32I, G48V, I54ALMSTV, V82F, and L90M were associated with decreased susceptibility to six to seven PIs; I47A, G48M, I50V, L76V, V82ST, and N88S were associated with decreased susceptibility to four to five PIs; and D30N, PMID: 18992847

Infection, genetics and evolution
Abstract: V82L mutation was present with increased frequency in isolates from children compared to isolates from adults infected with both subtypes.
Result: Only V82L was present with increased frequency in subtype B (6.7%) and F1 (8.3%, not shown) isolates from children compared to subtype B (0%) and F1 (0.8%) isolates from adults (Table 2).
Table: V82L
Discussion: Interestingly, V82L reported by IAS consensus as a major mutation specifically associated with resistance to tipranavir, not used by our cohort, was observed in subtypes B and F1 isolated from treated children but not in adults.

Abstract: Only two major mutations, M46L and V82L, were separately found in three individuals of 71 (4.2%) with one carrying both mutations.
Population trends in the prevalence and patterns of protease resistance related to exposure to unboosted and boosted protease inhibitors.
Abstract: Individual mutations L33F, M461/L, V82A/F/T/S/L and 184V became relatively more frequent over the period of study.

Abstract: In multivariable models adjusting for prior AIDS, baseline CD4 counts, HIV-1 RNA, and calendar year, viral resistance variables associated with increased hazards of clinical progression were the presence of reverse transcriptase substitution T215F (p = 0.002) and the presence of three or more protease substitutions among L33F/I/V, V82A/F/L/T, I84V, and L90M (p = 0.003).

Abstract: During in vitro selection, A-790742 selected two primary mutations (V82L and I84V) along with L23I, L33F, K45I, A71V/A, and V77I in the pNL4-3 background and two other mutations (A71V and V82G) accompanied by M46I and L63P in the HIV-1 RF background.
Abstract: HIV-1 pNL4-3 clones with a single V82L or I84V mutation were phenotypically resistant to A-790742 and ritonavir.
