HIV-1 subtype diversity, drug resistance, and genetic transmission networks in men who have sex with men with virologic failure in antiretroviral therapy in Sichuan, China, 2011 to 2017.
Result: K103N/KN (155/372, 41.67%), V106M/MA/MV (107/372, 28.76%), G190A/AG/S (103/372, 27.69%), and Y181C/CY (89/372, 23.92%) were the major NNRTI-related mutations.
Discussion: We observed that K103N/KN, V106M/MA/MV, G190A/AG/S, and Y188L/C are the major NNRTI-related mutations in China and other countries, which may be the result of the wide-spread use of NNRTIs.
HIV Drug Resistance after Failure of 6 Month First-line Therapy in a Hospital: A Case Series.
Abstract: M184V/I, K103N/S, and G190A/S/E were the most common mutations detected.
Result: The most common mutations were M184V/I (45; 53.6%), K103N/S (41; 48.8%), and G190A/S/E (20; 23.8%).
Discussion: M184V/I, K103N/S, and G190A/S/E were the most common mutations detected among those patients.

Oxidative medicine and cellular longevity
Result: G190S and K103N have little effect on RT-driven polymerization but selectively slow down RNase H cleavage and delay initiation of DNA synthesis, resulting in a significant reduction of viral replication competence.
Result: Based on this, we designed RT_A with M184V and K65R/N (RT_An) and RT_A with K103N and G190S (RT_Ann) which we predicted to have reduced polymerase and RNase H activities, respectively.
Result: Mutations M184V/K65R or K103N/G190S were introduced into p6HRT_A by site-directed mutagenesis, yielding plasmids for prokaryotic expression o
HIV-genetic diversity and drug resistance transmission clusters in Gondar, Northern Ethiopia, 2003-2013.
Result: Taken together, the G190A/S/E mutations were most prominent (seven of the 12 NNRTI mutations), followed by the K103N, Y181I/C and K101E substitutions (two, two and one, respectively).
Result: Two had K103N, one G190S and one Y181C, all representing resistance to non-nucleoside reverse transcriptase inhibitors (NNRTI).

HIV-1 infection among crack cocaine users in a region far from the epicenter of the HIV epidemic in Brazil: Prevalence and molecular characteristics.
Abstract: Isolates from two participants showed mutations associated with resistance to nucleoside reverse transcriptase inhibitors (NRTI) only (M41L, T125C, T125F, M184V), while an isolate from one patient who had received antiretroviral therapy (ART) since 2008 had a mutation associated with resistance to non-NRTI (G190S).
Prevalence of HIV-1 pretreatment drug resistance among treatment naive pregnant women in Bissau, Guinea Bissau.
Abstract: Four carried mutations exclusively linked to non-nucleoside reverse transcriptase inhibitors (NNRTIs) (K103N, K103N/S) and one carried mutations to both NNRTIs (
Result: Four carried mutations towards NNRTI only (K103N and K103N/S) and one carried mutations to both NNRTI (G190S, K101E) and NRTI (M184V) No DRM toward protease inhibitors (PIs) was found.

Long-term virological outcome in children receiving first-line antiretroviral therapy.
Result: K103N (48%), Y181C (37%), G190A/S (25%), Y188C/L (10%), V106M/A (8%), K65R (8%) and L100I (4%) were the major NNRTI DRMs observed in these 52 children.
