Abstract: In the remaining six patients, the following patterns of mutations associated with viral resistance were found: one mutation (K70R), which was observed in one patient during the 1st TI and persisted during follow-up; two mutations (L90M, M184V), which were observed in four patients during the 1st TI and were intermittently present or lost following extended TI, treatment reinitiation and/or during subsequent TI; and evolution of two mutations (M184V, K219E) observed in two patients.

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: 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.
Nucleoside analog resistance caused by insertions in the fingers of human immunodeficiency virus type 1 reverse transcriptase involves ATP-mediated excision.
Abstract: However, unlike the classic AZT resistance mutations (M41L/D67N/K70R/T215Y or F/K219E or Q), the combination of the amino acid insertions in the fingers and the T215Y mutation allows efficient excision of ddTMP and d4TMP, even when relatively high levels of deoxynucleoside triphosphates are present in the reaction.

Abstract: Prevalence of known drug resistance mutations revealed slightly significant differences among B and non-B subtypes: L10I, 21 and 64%, K20R, 13 and 43%, M36I, 34 and 100%, L63P, 76 and 36%, A71V/T, 24 and 0%, and V77I, 32 and 0%, respectively, in the protease (0.0001 D67N, 38 and 8%, K70R, 33 and 0%, R211K, 49 and 85%, and K219Q/E, 31 and 0%, respectively, in the reverse transcriptase (0.0256
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.

Abstract: Rapid failure was surprisingly associated with baseline presence of protease gene mutation L90M (P=.04) in the absence of D30N and with RT mutations D67N (P<.01), K70R/S (P=.02), and K219Q/W/R/E (P<.01).
