Result: 81.25 % (n = 13) had more than 1 NNRTI mutation.Y181C and G190A was the most common NNRTI mutation present in 37.5 % (n = 6) patient each.

Result: As previously reported in this group of well characterized patients, two patients had NNRTI associated mutations (G190A and E138G) and one patient had a NRTI resistance-associated mutation (L210 W).

HIV-1 subtype characteristics of infected persons living in southwestern Greece.
Result: The 22 cases experiencing virologic failure presented with the following DRMs: M46I, F53LY, I54LTV, G73ST, L76V, V82AT, I84V, I185V, N88D, and L90M for PIs; L100I, K103NS, V179F Y181C, G190AS, V106A, K103N, and P225H for NNRTIs; and
HIV-1 Drug Resistance Mutations: Potential Applications for Point-of-Care Genotypic Resistance Testing.
Result: K103N, Y181C and G190A were the three most common NNRTI DRMs in all regions and subtypes, occurring in more than 60% of viruses with intermediate or high-level
Result: Fig 2 shows that the most common NNRTI DRMs in viruses from individuals in LMICs with intermediate or high-level resistance on a first-line NRTI/NNRTI-containing regimen were K103N (45.5%), Y181C (27.0%), G190A (21.0%), and V106M (18.7%).

Abstract: RESULTS: Sixteen mutations at 10 positions were significantly associated with the greatest contribution to reduced phenotypic susceptibility (>=10-fold) to one or more NNRTIs, including: 14 mutations at six positions for nevirapine (K101P, K103N/S, V106A/M, Y181C/I/V, Y188C/L and G190A/E/Q/S); 10 mutations at six positions for efavirenz (L100I, K101P, K103N, V106M, Y188C/L and G190A/E/Q/S); 5 mutations at four positions for etravirine ( PMID: 24164431

Abstract: The specific SDRMs detected were M41L for nucleoside reverse transcriptase inhibitors (NRTIs) and G190A for nonnucleoside reverse transcriptase inhibitors (NNRTIs).
HIV-1 virologic failure and acquired drug resistance among first-line antiretroviral experienced adults at a rural HIV clinic in coastal Kenya: a cross-sectional study.
Result: K101E and G190A caused high resistance to NVP, intermediate resistance to EFV, and low resistance to ETR and RPV.
Result: G190A accounted for 1.9%, and caused high level resistance to NVP and intermediate resistance to EFV.
Result: HNHIV46, HNHIV74, HNHIV77, and HNHIV137 were clustered together, with HNHIV46 and HNHIV137 having A71V, D67N, K101E, and G190A mutations, HNHIV74 having A71T mutation, and HNHIV77 having A71V and K103N mutations.

Discussion: In a study conducted in Gondar, only two mutations (V75I and G190A) were detected among 92 ART-naive patients in 2003, before ART roll out.
