Result: For the PIs mutations that are accurately reproduced include D30N, I50L, V82S, and I84, while the I64L and I93M mutations are assigned less importance than in previous work.

Antiviral resistance and correlates of virologic failure in the first cohort of HIV-infected children gaining access to structured antiretroviral therapy in Lima, Peru: a cross-sectional analysis.
Method: The OLA was conducted according to the NIH protocol for mutations at HIV-1B protease positions D30N, I50V, V82A, V82S, V82T, I84V, N88D, and L90M as well as reverse transcriptase positions K103N, Y181C, K65R, T215F, T215Y, M184V, and Q151M.

Introduction: Mutations of V82A/T/F/S/L are very common in PI resistance and show reduced susceptibility to all the clinical PIs except DRV.
Does GSS still maintain relevance on HAART outcome after the introduction of newest active antiretroviral drugs? 48 weeks results.
Method: The final list of mutations included M41L, E44D, D67N, T69D, K70R, L74V, L100I, K103N, V108I, V118I, Y181C, M184V, G190A, L210W, T215F, T215Y and K219Q in RT; and L33F, L33I, M46I, M46L, G48V, <

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: 20587857

Antiviral therapy
Abstract: Mutations V82A/F/T/S/M/I were primarily selected by the administration of ritonavir (RTV) in an historical ARV regimen.
Abstract: RESULTS: In protease (PR), resistance-associated mutations M46I/L, I54M/L/V/A/S and V82A/F/T/S/M/I were associated with each other and with minor mutations at codons 10, 24 and 71.
Clinical validation and applicability of different tipranavir/ritonavir genotypic scores in HIV-1 protease inhibitor-experienced patients.
Abstract: On the contrary, the use of T20 in T20-naive patients and the V82AFSI and F53LY non-IAS mutations were associated with virological success.

Infection, genetics and evolution
Method: Mutations D30N (NFV), V32I (LPV), M46I/L (IDV/RTV), I47V/A (LPV/RTV), G48V (SQV), I50L/V (APV), V82A/F/T/S (LPV/IDV/RTV), I84V (APV/IDV/RTV) and L90M (SQV/NFV) were considered as major resistance mutations and were analyzed separately for each PI as well as quantitatively all together.
Result: Ninety-seven percent of isolates with V82A/F/T/S mutations were from patients treated with IDV, RTV and/or LPV, and 89% of those with L90M were from patients treated with NFV and/or SQV.
