Abstract: Different patterns of covariation were frequently observed for different mutations at the same position including the RT mutations T69D versus T69N, L74V versus L74I, V75I versus V75M, T215F versus T215Y, and K219Q/E versus K219N/R, and the protease mutations M46I versus M46L, I54V versus I54M/L, and N88D versus N88S.

Impact of HIV-1 reverse transcriptase polymorphism at codons 211 and 228 on virological response to didanosine.
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: 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.
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: 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%).
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%).

Abstract: Among mutations associated with high-level resistance to RTI, T215Y was found in only 2 patients, M184V in 2 cases, T69D in another case, and K103N in only 1 patient, for a total of 6 patients (one carrying both T215Y and M184V) (1.7%).
