Transmitted HIV-1 drug resistance in a large international cohort using next-generation sequencing: results from the Strategic Timing of Antiretroviral Treatment (START) study.
Result: Patients infected with the CRF01_AE subtype were the most likely to develop NRTI-associated mutations; the most common mutations were M41L (0.17%) and D67G (0.17%).
HIV-1 subtypes and drug resistance in children during antiretroviral therapy in Brazil.
Abstract: The most common primary mutations found were M184V (29.5%), K103N (25%), M41L (9.8%), T215Y (8.3%), and G190A (8.3%).
Virologic outcomes of switching to dolutegravir functional mono- or dual therapy with a non-cytosine nucleoside analog: a retrospective study of treatment-experienced, patients living with HIV.
Result: The other patient was switched from TDF/FTC/EVG/c to DTG/ABC/3TC (Table 2, Patient 6) and historical genotypic testing revealed an M184V/I, M41L, T215Y and L74/I which predicted that DTG was the only fully active agent in the study DCR.
Table: M41L
Discussion: Among the three patients on functional dual therapy with persistent viremia and documented non-adherence, two were on DTG/ABC and only had baseline M184V/I whereas the other was on DTG/TDF and had baseline M184V/I, M41L and T215Y.
Discussion: The other was on DTG/ABC/3TC and had baseline M184V/I, L74I, M41L
Temporal Trends in HIV-1 Mutations Used for the Surveillance of Transmitted Drug Resistance.
Result: Thymidine analog mutations (TAM) were detected in 35.4% of the individuals [17.1% (14/82) TAM-1 (including M41L, L210W, and T215Y) and 20.7% (17/82) TAM-2 (including D67N, K70R, T215F, and K219Q/E)].

Method: The variables expressing NRTI RAMs were identified as follows: (1) presence versus absence of any NRTI RAM; (2) presence versus absence of at least 1 TAM (M41L, D67N, K70R, L210W, T215Y/F, K219Q/E); (3) presence versus absence of M184V/I (with or without other RAMs); (4) presence versus absence of M184V/I not associated with TAMs; (5) presence versus absence of M184V/I combined with at least 1 TAM.

Abstract: The most common DRMs of these three subtypes were K103N and M184V, while the mutation frequencies of M41L, D67N, K70R, K101E, V106M, Y181C, K219E, H221Y and N348I were obviously different among subtypes.
