Discussion: Some SDRMs, including NRTI-related mutations (M41L, D67E/G/N, K70E/R, M184V, T215any, and K219any) and NNRTI-related mutations (K101E/P, K103N/S, V106A/M, Y181any, G190any, and P225H) were reported in Myanmar.

Abstract: Clinically relevant combinations of TAMs, such as M41L/T215Y or D67N/K70R/T215F/K219Q, enhance the ATP-mediated excision of AZT monophosphate (AZTMP) from the 3' end of the primer, allowing DNA synthesis to continue.
Abstract: In HIV-1, development of resistance to AZT (3'-azido-3'-deoxythymidine) is mediated by the acquisition of thymidine analogue resistance mutations (TAMs) (i.e., M41L, D67N, K70R, L210W, T215F/Y, and K219E/Q) in the viral reverse transcriptase (RT).
Prevalence and characteristics of HIV drug resistance among antiretroviral treatment (ART) experienced adolescents and young adults living with HIV in Ndola, Zambia.
Abstract: Common TAMs were K70RTQNE (32.8%), K219QE (22.4%), D67N (17.2%) and T215IT (15.5%).
Discussion: In terms of HIVDR to NRTI, the prevalence of any TAMs was at 32.8% and the most common TAM's were K70R/T/Q/N/E (32.8%), K219Q/E (22.4%), D67N (17.2%), T215IT (15.5%) and M41L (5.2%).
Discussion: The high prevalence of individual TAMs (D67N and K70R) or TAMs in combination (M41L with T215Y) reduces susceptibility to Zidovudine (a ke
Patterns of acquired HIV-1 drug resistance mutations and predictors of virological failure in Moshi, Northern Tanzania.
Discussion: M184V associates with high-level resistance to abacavir, emtricitabine, and lamivudine; while K70R and D67N are among the TAMs.
Discussion: This study further reports frequent NRTI resistance-associated mutations as M184V, K70R, and D67N in line with other studies.
Comparison of HIV drug resistance profiles across HIV-1 subtypes A and D for patients receiving a tenofovir-based and zidovudine-based first line regimens in Uganda.
Result: This was followed by K70R, K65R and K219 mutations occurring at 56 (24.3%), 42 (23.1%) and 40 (22%) respectively.

Abstract: The susceptibilities to antiviral drugs of site-directed mutants (SDMs) and patient-derived mutants containing combinations of TAMs (M41L, D67N, K70R, L210W, T215Y, and K219Q) with or without the M184V mutation (TAMs+-M184V) were evaluated using either 5-day multicycle (MC; n = 110) or 2-day single-cycle (SC; n = 96) HIV assays.

Abstract: In RT, 9 nonpolymorphic TSMs occurred in >=10 persons: K40R, A62V, K70R, Y115F, Q151M, M184VI, S215Y.
Pre-treatment HIV-drug resistance associated with virologic outcome of first-line NNRTI-antiretroviral therapy: A cohort study in Kenya.
Discussion: Compared to Sanger sequencing, the OLA used in this study identified PDR in all but one participant (with K70R) who subsequently experienced virologic failure.
