Abstract: Fourteen major mutations of codon 99-191 on the RT gene were selected (K103N, V106A/M, V108I, Q151M, Y181C/I, M184V/I, Y188C/L/H, and G190S/A) at a cost of testing of 35 USD.
Method: This region was selected to cover 14 mutations (K103N, V106A/M, V108I, Q151M, Y181C/I,
Result: No patients had the mutations Y188C/L/H and Q151M.
Deep sequencing analysis of HIV-1 reverse transcriptase at baseline and time of failure in patients receiving rilpivirine in the phase III studies ECHO and THRIVE.
Abstract: At failure, two patients without NNRTI RAMs by PS carried minority rilpivirine RAMs K101E and/or E138K; and five additional patients carried other minority NNRTI RAMs V90I, V106I, V179I, V189I, and Y188H.

Abstract: Nonnucleoside reverse transcriptase inhibitor-associated TDRMs were detected in 3.3% (44/1,306) of patients (L100I, K101E/P, K103N/S, V179F, Y188H/L/M, Y181I/C, and G190A/E/S) and TDRMs to protease inhibitors were detected in 2.3% (30/1,306) of patients (M46L, I50V, I54V, Q58E, L76V, V82A/C/L/T, N83D, I84V, and L90M
HIV-1 Drug Resistance Mutations: Potential Applications for Point-of-Care Genotypic Resistance Testing.
Figure: Major NNRTI-associated DRMs (HIVDB score >=60) included: L100I, K101P, K103N/S, V106A/M, Y181C/I/V, Y188L/H/C, G190A/S/E/Q, and M230L.
A post-partum single-dose TDF/FTC tail does not prevent the selection of NNRTI resistance in women receiving pre-partum ZDV and intrapartum single-dose nevirapine to prevent mother-to- child HIV-1 transmission.
Result: Fifteen (34%) patients had mutations (viz K103N, Y181C, Y188C, Y188HY, and G190AG) associated with high level resistance to NNRTI, in particular NVP, whilst 1 (2%) patient had K101E associated with intermediate resistance to NNRTIs.

Abstract: RESULTS: The patients had TDRMs to NRTIs (K65R, M184V), NNRTIs (K101E, K103N/S, G190A/E/S, Y181I/C, Y188H/L) and PIs (M46L, I54V, L76V, V82L/T, N83D, I84V, L90M).

Abstract: While for B subtype, the major resistance mutations include M184V, K103N,Y181C, T69N,G190A, K238T,Y188H and P225H.
Distinct resistance patterns to etravirine and rilpivirine in viruses containing nonnucleoside reverse transcriptase inhibitor mutations at baseline.
Abstract: However, subtype B viruses containing Y181C generated V179I/F or A62V/A but not E138K following exposure to ETR or RPV, respectively, whereas subtype C viruses containing Y181C developed E138V together with Y188H and V179I under ETR pressure.
