Method: In total, 94 of 100 samples from patients failing ARV treatment also carried HIV-1 NRTI resistane mutations including M184V (82%), K65R (35%), L74I (19%), M41L (17%) or D67N (17%).

Abstract: Here, we demonstrate that mutant M41L/D67N/K70R/S215Y HIV-2 RT lacks ATP-dependent excision activity, and recombinant virus containing this RT remains susceptible to AZT inhibition.
Abstract: Interestingly, recombinant HIV-2 carrying a mutant D67N/K70R/M73K RT showed 10-fold decreased AZT susceptibility and increased rescue efficiency on AZT- or tenofovir-terminated primers, as compared with the double-mutant D67N/K70R.

Introduction: Based on significant previous research of DRMs, TAMs have been described to associate into one of two distinct pathways: TAM-1 (M41L, L210W, T215Y) or TAM-2 (D67N, K70R, T215F, K219E/Q).
Introduction: For all TAMs, with the exception of K219E, D67N, and K70R, there was no acquisition from S1 to S2 in patients on TDF, whereas the mean acquisition rates of individual TAMs in the patients on AZT varied from 0.005 mutations per month to 0.019 mutations per month.
Introduction: However, three males in the study exhibited the K65R, K219E +- PMID: 28627486

Abstract: Among individuals with at least one DRM, we found evidence that any nucleoside/nucleotide reverse transcriptase inhibitor (NRTI) resistance, the reverse transcriptase (RT) mutations M184V, D67N and T215Y as well as the protease mutations V82A and I54V were associated with reduced CD4 declines.

Abstract: The most common mutations detected at >20% and 2%-20% mutation frequency differed for each drug class, these respectively being: L90M (n = 7) and M46IL (n = 10) for PIs; T215rev (n = 9) and D67GN (n = 4) for NRTIs; and K103N (n = 5) and G190E (n = 2) for NNRTIs.
Early virological failure and HIV drug resistance in Ugandan adults co-infected with tuberculosis.
Result: In NRTI coding regions, M184V/I was the most frequent mutation, accounting for 30.4% (65/214), followed by K70R (8.4%, 18/214), D67N (5.6%, 12/214), M41L (5.4%, 11/214), and T215Y (5.4%, 11/214).
Result: Two participants infected through homosexual contact and one participant infected through heterosexual contact harbored NRTI mutations D67N and M184V, and NNRTI mutation K103N.

Result: After adjustment, participants on zidovudine at failure were more likely to have T215F, T215Y, M41L, K70R, D67N, L210W, type-1 thymidine analog, type-2 thymidine analog, and any thymidine analogue mutations (TAMs); those on tenofovir to have K65R, K70E, Y115F, and M184I; those on efavirenz to have K103N, P225H, Y188L, and L100I; and those on nevirapine to have Y181C and G190A.
