Result: Transmitted drug resistance mutations (tDRM), based on WHO mutation list, were observed in one (0.6%) protease (L54M mutation), 6 (3.8%) NRTI (mutations in the codon positions: M41L, D67N, T215S/V, K219Q) and two (1.1%) (both E138K mutations) integrase sequences (supplemental table 2).
Discussion: As expected the most common NRTI DRMs were thymidine analog mutations, namely M41L, D67N, T215S/V, K219Q, associated with high levels of resistance to zidovudine, but also affect the abaca
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)].

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.
HIV-1 molecular transmission network among sexually transmitted populations in Liaoning Province, China.
Result: Among them, 9 cases were protease inhibitor-related resistance, and the main resistance sites were L33F, V82A, Q58E, M46L, M46I; There were 4 cases of nucleoside reverse transcriptase inhibitor resistance, the main mutation sites were V75VI, K219Q, T215A, K65R; There were 5 cases of non-nucleoside reverse transcriptase inhibitor resistance, the main mutation sites were V179E, A98G, V106I, Y181C, G190S
Prevalence and factors associated with HIV-1 drug resistance mutations in treatment-experienced patients in Nairobi, Kenya: A cross-sectional study.
Result: K65R/E/N and K70E mutations conferred resistance to TDF and M41L, D67N, K70R, L210W, T215Y/F, and K219Q/E conferred resistance to AZT.
Result: M184 V/I 87 (28.8%), K65R/E/N 27 (8.9%), L74 V 3 (1.0%), and Y115F 12 (4.0%) were the mutations conferring resistance to NRTIs, along with thymidine analog mutations (TAMs) M41L 14 (4.6%), D67N 17 (5.6%), K70R 20 (6.6%), L210W

Abstract: To study EFdA resistance patterns that may emerge in naive or tenofovir (TFV)-, emtricitabine/lamivudine (FTC/3TC)-, or zidovudine (AZT)-treated patients, we performed viral passaging experiments starting with WT, K65R, M184V, or D67N/K70R/T215F/K219Q HIV-1.
Phylogenetic and Drug-Resistance Analysis of HIV-1 Sequences From an Extensive Paediatric HIV-1 Outbreak in Larkana, Pakistan.
Abstract: Of the treatment-naive participants, the two most common mutations were RT: E138A (8%) and RT: K219Q (8%).
Result: Among ART naive individuals, 15 (30%) had drug resistance mutations (DRM); the most common of which were the Reverse Transcriptase (RT):E138A (8.0%) and RT:K219Q (8.0%) mutations.
Result: Among t
Result: Among the 78 sequences from the Larkana outbreak with prevalent drug resistance mutations, the DRM RT:K219Q was shared between five sequences whereof all clustered together in cluster_CRF02_AG_1 (Tables 2, 3).
