Abstract: When used with ritonavir, the accumulation of six or more mutations among L10F/I/V, K20M/R, E35D, R41K, I54V, L63P, V82A/F/T/S and I84V leads to clear decrease in viral response to treatment.

Abstract: For the IP: key mutations L90M (26.1%), M46I (18.1%) and V82AFTS (12.9%); and accessory mutations L63P (50.5%), A71V (27.2%), L10I (25.2%) and M36I (19.2%).

Abstract: In particular, E34Q, K43T, and K55R, which were associated with lopinavir treatment, correlated with mutations associated with lopinavir resistance (E34Q with either L33F or F53L, or K43T with I54A) or clustered with multi-PI resistance mutations (K43T with V82A and I54V or V82A, V32I, and I47V, or K55R with V82A, I54V, and M46I).

Abstract: A surprisingly diverse pattern of primary PI mutations was seen: M46I (n=7), D30N (n=6), L90M (n=5), and V82A (n=4).
Abstract: At baseline, the V82A mutation was found in four PI-naive patients of whom two failed therapy exhibiting this mutation.

Abstract: Children with I54V and V82A/F had higher prevalence of lopinavir-associated resistance mutations and showed RP of 0.36 (CI95%: 0.17; 0.76; P = 0.007) for achieving uVL.
Abstract: Moreover, I54V and V82A/F led to the poorest virological response.
Abstract: The relative proportion (RP) to uVL was 0.32 (CI95%: 0.16; 0.33; P = 0.002) in children with I54V (46% of total) and 0.48 (CI95%: 0.24; 0.97; P = 0.041) in children with V82A/F (52% of total).
Molecular basis for substrate recognition and drug resistance from 1.1 to 1.6 angstroms resolution crystal structures of HIV-1 protease mutants with substrate analogs.
Abstract: PR(V82A) was able to compensate for the loss of interaction with inhibitor cause
Abstract: HIV-1 protease (PR) and two drug-resistant variants--PR with the V82A mutation (PR(V82A)) and PR with the I84V mutation (PR(I84V))--were studied using reduced peptide analogs of five natural cleavage sites (CA-p2, p2-NC, p6pol-PR, p1-p6 and NC-p1) to understand the structural and kinetic changes.

Table: V82A
Discussion: Other mutations resulting from G A transitions may occur rarely, such as V82T (the preferred mutation in this position is V82A, which results from a T C transition).
