Result: In addition, the OLA did not detect resistance to NNRTI in one participant with V106M and Y188C, or resistance to 3TC in four participants with M184I, as these mutations were not interrogated by the OLA.
HIV-1 Drug Resistance, Distribution of Subtypes, and Drug Resistance-Associated Mutations in Virologic Failure Individuals in Chengdu, Southwest China, 2014-2016.
Result: K103N (37.55%, 92/245) was the most frequent mutation, followed by G190A/E/K/Q/S/V (28.57%, 70/245), V179I/D/E/T (27.76%, 68/245), V106A/I/M (26.12%, 64/245), Y181C/V (18.78%, 46/245), K101E/H/P (14.69%, 36/245), Y188C/H/L (5.71%, 14/245), L100I (4.08%, 10/245), and M230L (4.08%, 10/245).

Discussion: In this NNRTI-experienced population (N = 6893), intermediate-level (defined as detection of any RT V106A/M, Y188C/H, V108I, and K103N + P225H substitution) and high-level (defined as detection of any RT Y188L, M230L, G190E, V106A/M + F227L, and V106A/M + L234I substitutions) DOR resistance was seen in 12.7% and 6.1%, respectively, and the most common high-level DOR resistance-associated substitution was PMID: 32381145

Epidemiology and infection
Abstract: Among the DRMs detected, some independently conferred resistance, such as K65R (1.6%, 5/322), Y188C/F/L (0.9%, 3/322), K103N (0.6%, 2/322) and G190A (0.3%, 1/322), which conferred high-level resistance.
Result: Among the key DRMs for NNRTIs, Y188C/F/L (0.9%, 3/322), K103N (0.6%, 2/322) and G190A (0.3%, 1/322) conferred high-level resistance, K101E (0.9%, 3/322) and P225H (0.9%, 3/322) conferred intermediate resistance and H221Y (0.9%, 3/322) conferred low-level resistance.
Prevalence and characteristics of HIV drug resistance among antiretroviral treatment (ART) experienced adolescents and young adults living with HIV in Ndola, Zambia.
Abstract: Emergence of these mutations including the NNRTI associated mutations (Y181C and Y188C) may compromise future second- and third-line regimens in the absence of routine HIVDR testing.
Abstract: There was a relatively high occurrence of other NNRTI mutations V106A (36.2%), as well as Y188C (36.2%) and Y181C (36.2%) which confer resistance to etravirine.
Result: Overall, the 10 most common mutations were M184V (81%), K103N (65.5%), Y188C (36.2%), Y181C (36.2%), V106A (36.2), K65R (34.5%),
HIV-1 re-suppression on a first-line regimen despite the presence of phenotypic drug resistance.
Result: The prevalence of other major NNRTI resistance mutations (Y181CS, Y188CH, G190A and M230L) was <=8%.

Drug resistance evolution in patients with human immunodeficiency virus-1 under long-term antiretroviral treatment-failure in Yunnan Province, China.
Discussion: We observed that NNRTI mutations principally occurred in the first and second periods of treatment failure and were mainly K103 N/R/S, V179D/E, Y181C/I/V, G190A, Y188L/C.

Abstract: Intermediate DOR resistance was defined as detection of any of V106A/M, Y188C/H, V108I, and K103N+P225H.
