Result: Sixteen participants had all of the TAM 1 pathway mutations (M41L, L210W and T215Y), 11 had all of the TAM 2 pathway mutations (D67N, K70R, T215F and K219Q/E) and four had the mutations for both pathways.

HIV Drug Resistance Mutations Detection by Next-Generation Sequencing during Antiretroviral Therapy Interruption in China.
Result: However, some minority DRMs at frequencies of 1%-5% disappeared, including N83D with PI-related, K70E, T215A, and K219E with NRTI-related and K101E, Y181C, H221Y and K238T with NNRTI-related, while others emerged, such as NNRTI-related V106A in patient GX088 at a frequency of 8.7%, and L23I, I47V and I84V with PI-related, D67N and
Temporal Trends in HIV-1 Mutations Used for the Surveillance of Transmitted Drug Resistance.
Method: Thymidine-analog mutations were defined as the NRTI-SDRMs M41L, D67N/G/E, K70R, L210W, T215Y/F/S/C/D/E/I/V, and K219Q/E/N/R.
High HIV-1 Virological Failure and Drug Resistance among Adult Patients Receiving First-Line ART for At least 12 Months at a Decentralized Urban HIV Clinic Setting in Senegal before the Test-and-Treat.
Result: Nonetheless, in patient 279A K70R co-occurred with K219E, the TAM variant D67G, and T69D, suggesting undisclosed use of AZT (http://hivdb.stanford.edu).

High Detection Rate of HIV Drug Resistance Mutations among Patients Who Fail Combined Antiretroviral Therapy in Manaus, Brazil.
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)].
Transmitted HIV-1 drug resistance in a large international cohort using next-generation sequencing: results from the Strategic Timing of Antiretroviral Treatment (START) study.
Abstract: Using the 2% detection threshold, individual DRMs with the highest prevalence were: PI M46IL (5.5%), RT K103NS (3.5%), RT G190ASE (3.1%), T215ISCDVEN (2.5%), RT M41L (2.2%), RT
Discussion: The most commonly detected NRTI DRMs, K219QENR and M184VI, occurred predominately as minor variants while the majority of patients with T215 revertants had the mutation in > 80% of the quasispecies.
