Abstract: Nucleoside analog mutations (NAMs) (M41L, D67N, K70R, L210W, T215Y/F and K219Q/E) are associated with reduced susceptibility to most nucleoside analogs and the nucleotide tenofovir.
Abstract: This recently approved drug has shown a reduced virologic response in the presence of three or more NAMs, including M41L or L210W, as well as in the presence of T69 insertions.

Abstract: The overall analysis of drug resistance mutations in viruses from treated subjects has highlighted some associations between subtypes and particular mutations, such as V82A/F/T/S in protease and subtype F1 and M41L and L210W in RT and subtype B.

Abstract: There are several major genetic mutational patterns of resistance and cross-resistance that evolve with the NRTIs including the thymidine analog mutations M41L, D67N, K70R, L210W, T215Y, and K219Q/E/W, the non-thymidine mutations M184V, L74V, and K65R, and the multidrug resistant Q151M complex, as well as others.
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.
[Mutations of resistance of HIV-1 in previously untreated patients at penitentiary centers of the Autonomous Community of Valencia, Spain. REPRICOVA study].
Abstract: With regard to NIRT, 7 samples (5.2% of total) showed some mutation of resistance: M41L, D67N, L210W and K219Q, all them secondary to and associated with resistance to zidovudine, abacavir as well as group B multinucleoside-resistance.

Abstract: As expected, E44A/D and V118I mutations were strongly associated with M41L, D67N, L210W, and T215Y but also with other mutations, including K43E/N/Q, T69D, V75M, H208Y, R211K, and K219R.

Abstract: The frequencies of K70R, T215S/Y/F (i.e., mutation of T at codon 215 to S, Y, or F), D67N/E, K219Q, T69N/S/A, M41L, and L210W mutations conferring resistance to zidovudine were 57.6, 36.4, 36.4, 27.2, 24.2, 21.2, and 12.1%, respectively.
M184V is associated with a low incidence of thymidine analogue mutations and low phenotypic resistance to zidovudine and stavudine.
Abstract: The number of thymidine analogue mutations (TAMs) was lower in isolates with M184V, this was independent of plasma HIV-1-RNA level and time on therapy for T215F/Y, D67N and L210W.
Thymidine analog and multinucleoside resistance mutations are associated with decreased phenotypic susceptibility to stavudine in HIV type 1 isolated from zidovudine-naive patients experiencing viremia on stavudine-containing regimens.

Abstract: Studies have demonstrated that HIV-1 isolated from subjects experiencing virologic failure on stavudine (d4T)-containing regimens often contains thymidine analog mutations (TAMs), consisting of reverse transcriptase (RT) mutations M41L, D67N, K70R, L210W, T215Y/F, and K219Q/E, previously associated only with zidovudine (ZDV) resistance.
Mutational patterns in the HIV genome and cross-resistance following nucleoside and nucleotide analogue drug exposure.
Abstract: These six mutations (M41L, D67N, K70R, L210W, T215Y/F, K219Q) enhance RT pyrophosphorolysis to confer high-level viral resistance to zidovudine, and clinically significant loss of response to stavudine and didanosine.
