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
Discussion: The specific NNRTI associated mutations found in this study (K103N, G109S and Y181C) have been reported to account for the most common NNRTI-associated mutations in all world regions and HIV subtypes.
Virologic suppression in response to antiretroviral therapy despite extensive resistance within HIV-1 reverse transcriptase after the first virologic failure.
Discussion: However, some studies have shown that NVP-containing ARVs have repercussions on the response to etravirine for selecting the Y181C and G190A mutations, whereas the K103 mutation associated with EFV does not interfere with etravirine susceptibility.
Research on the treatment effects and drug resistances of long-term second-line antiretroviral therapy among HIV-infected patients from Henan Province in China.
Abstract: At the time of virologic failure, multiple NNRTI-associated mutations were observed: 80%-K103N and Y181C being the major NNRTI mutations-observed.
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 childre
Discussion: Among those who developed VF, M184V, K103N, and Y181C were the most common DRMs observed as in South Africa.
HIV-1 subtype diversity, transmission networks and transmitted drug resistance amongst acute and early infected MSM populations from Coastal Kenya.
Result: The most frequently detected mutations were T215 revertants (not F/Y) (268; 1.6%) and other TAMs [M41L (141; 0.9%) and K219Q/N (104; 0.6%)] conferring resistance to the NRTI drug class; K103N (354; 2.2%) and Y181C (66; 0.4%) conferring resistance to the NNRTI drug class, and L90M (111; 0.7%) and M46L (48; 0.3%) conferring resistance to the PI drug class.

Abstract: All TDR mutations (M46L/I, Y181C, K101E, and G190E) were found only in youths infected with HIV-1 through sexual activity.
Abstract: TDR mutations resided in CRF01_AE (M46I/L and G190E) and subtype B (Y181C and K101E).

Abstract: Furthermore, most compounds maintained high activity agaist various single HIV-1 mutants (L100I, K103N, E138K, Y181C) as well as one double mutant (F227L/V106A) with EC50 values in low-micromolar to double-digit nanomolar concentration ranges.

Abstract: The analytical sensitivities of the HRMA assays were 5% of mixed species for K103N and Y181C and 20% for M184V.
Abstract: When applied to 153 HIV-1 patient specimens previously genotyped by Sanger population sequencing, HRMA correctly assigned drug sensitivity or resistance profiles to 80% of the samples at codon 103 (K103K/N) (Cohen's kappa coefficient [kappa] > 0.6; P < 0.05), 90% at 181 (Y181Y/C) (kappa > 0.74, P < 0.05), and 80% at 184 (M184M/V) (kappa > 0.62; P < 0.05).
Use of Capillary Electrophoresis to Study the Binding Interaction of Aptamers with Wild-Type, K103N, and Double Mutant (K103N/Y181C) HIV-1 RT : Studying the Binding Interaction of Wild-Type, K103N, and Double Mutant (K103N/Y181C) HIV-1 RT with Aptamers by Performing the Capillary Electrophoresis.

Abstract: Therefore, we utilized non-equilibrium capillary electrophoresis of equilibrium mixture (NECEEM) to study the interaction of three HIV-1 RTs (wild type, K103N, and double mutant (K103N/Y181C)) with RT1t49 and RT12 aptamers.
