Abstract: A mutation score (M41L+D67N+T69D-K70R +L74V-M 1 84V/I+T21 5Y/F+ K219Q/E+ R211A/D/G/K/S+ L228H/M/R), including two RT polymorphisms not previously described to be associated with ddl resistance (211 and 228) and RT mutations previously described, was associated with a continuum of virological response and increased the predictability of virological response to ddl.
Comparison of tests and procedures to build clinically relevant genotypic scores: application to the Jaguar study.
Abstract: RESULTS: Eight mutations were associated with a reduced virological response to ddI: M41L, D67N, T69D, L74V, V1181, L210W, T215Y/F and K219Q/E and two mutations with a better virological response: K70R and M184V/I.
Abstract: The Jonckheere-Terpstra test for trend provided the combination of mutations (M41L+T69D-K70R+L74V-M184V /I+T215Y/F+ K219A/E) that were the most predictive for the week 4 virologi

Abstract: Eight mutations were associated with a reduced response to ddI, M41L, D67N, T69D, L74V, V118I, L210W, T215Y/F, and K219Q/E, and two mutations were associated with a better response, K70R and M184V/I.
Abstract: The best prediction of the virologic response to ddI was obtained with a composite score comprising mutations added and subtracted (set II, M41L + T69D + L74V+ T215Y/F + K219Q/E - K70R -

Abstract: Many mutations associated with reduced susceptibility to nucleoside or non-nucleoside reverse transcriptase inhibitors were detected: M41L (11%), E44D (4%), D67N (11%), T69D (2%), K70R (11%), L74V (2%), L100I (4%), K103N (18%), V118I (9%), Y181C (11%), M184V (18%), G190A (4%), T215Y (4%), and K219E (4%).
Genotypic determinants of the virological response to tenofovir disoproxil fumarate in nucleoside reverse transcriptase inhibitor-experienced patients.
Abstract: RESULTS: The strongest association with decrease in viral load was observed with a set of seven mutations (TDF mutation score) that consisted of M41L, E44D, D67N, T69D/N/S, L74V, L210W and T215Y/F RT mutations.

Abstract: In particular, three patients (4.8%) carried viral major mutations (T69D and M41L) associated with resistance to reverse transcriptase inhibitors, whereas only one showed the presence of M46L, which is correlated with partial resistance to some protease inhibitors.
Prevalence of mutations related to HIV-1 antiretroviral resistance in Brazilian patients failing HAART.
Abstract: The main mutation found in RT gene was the M184V (48%) followed by T69D/N (47%), T215Y/F (46%), M41L (39%), and L74V (7%).
Prevalence of the mutational pattern E44D/A and/or V118I in the reverse transcriptase (RT) gene of HIV-1 in relation to treatment with nucleoside analogue RT inhibitors.
Abstract: Multivariate analysis showed an association between the E44D/A and/or V118I mutational pattern and the RT mutations D67N, T69D, L210W, and T215Y/F.

Abstract: The selection of the T69D/N mutation in children with HIV-1 disease progression during ddI therapy suggests that this mutation confers a fitness advantage to the virus that may include resistance to ddI.
Abstract: Three viral parameters, syncytium-inducing phenotype, higher virus load, and mutation in HIV-1 pol encoding the T69D/N mutation, were associated with disease progression.
