Result: CS detected an additional 7 individuals with mutations conferring drug resistance to etravirine only (E38AV; V90IV; E138A; V179T; A98AG, V179T; V179DV; and A98G), who were wild-type at OLA codons.

Abstract: Mutations such as M184V/I (35.4%) in NRTIs and K103N/R/S/T (25.4%), V179D/E/T/Y (18.9%), G190A/E/R/S (13.8%), and Y181C (9.2%) in NNRTIs were common among the HIV-1 URF strains relative to other mutations.
Trend of HIV-1 drug resistance in China: A systematic review and meta-analysis of data accumulated over 17 years (2001-2017).
HIV-1 acquired drug resistance to integrase inhibitors in a cohort of antiretroviral therapy multi-experienced Mexican patients failing to raltegravir: a cross-sectional study.
Result: The K103N mutation was the most common, followed by E138A/G, G190A and A98G, and then V179D/E/T and Y181C (Table 2).

Natural polymorphisms in HIV-1 CRF01_AE strain and profile of acquired drug resistance mutations in a long-term combination treatment cohort in northeastern China.
Result: The NNRTI-associated DRMs detected at TF time point included G190S/C (66.7%), K101E/N/Q (52.4%), V179D/I/A/T/E (45.2%), Y181C (42.9%), K103R/N/S (42.9%), and V106 M (23.8%) (Table 1).
Table: V179D
Discussion: In this study, the polymorphisms at five known drug resistance-associated sites (V179I/D, V118I, K103R, K238R, and E40Q) were polymorphic accessory mutations or other mutations that did not independently decrease drug sensitivity.
Pharmaceutical, clinical, and resistance information on doravirine, a novel non-nucleoside reverse transcriptase inhibitor for the treatment of HIV-1 infection.
Introduction: Other substitutions such as V106M, V108I, V179D, Y188H, or P236L conferred less than 10-FC against DOR.
HIV-1 Drug Resistance, Distribution of Subtypes, and Drug Resistance-Associated Mutations in Virologic Failure Individuals in Chengdu, Southwest China, 2014-2016.
Abstract: Mutations associated with antiretroviral drugs include (V82A+I84IV), (L10F+Q58E), (L10F+V82Y), L10FV, L33LF, L89LMV, M184V, E138A, V106I, and V179VD.
Discussion: The E138A, conferring resistance to Rilpivirine, and Etravirine, V179VD confers resistance to Efavirenz, Etravirine, Nevirapine, and Rilpivirine, while V106I confers resistance to Etravirine, Nevirapine, Rilpivirine, and Doravirine.|m
