Method: Plasma samples contained a median of 3 [Q1-Q3: 2-4] NNRTI-associated drug resistance mutations which included A98G, L100I, K101E/H, K103N/S, V106M, V108I, E138A/K, V179D/E Y181C, Y188L/C, G190A, H221Y, P225H, F227L, and M230L.

Abstract: Results The most frequent mutations were M184V/I, K101E/P/H, K103N/S, D30N, M46L/I, I54L/M, V82T/F/A/S/L and L90M in adults and F77L, K103N/S, M46L/I, V82T/F/A/S/L and L90M in children.
HIV-1 transmitted drug resistance in Slovenia and its impact on predicted treatment effectiveness: 2011-2016 update.
Discussion: Equally fit are K103N, K103S, and Y181C mutations, which were detected in four individuals from Slovenia.
Virologic suppression in response to antiretroviral therapy despite extensive resistance within HIV-1 reverse transcriptase after the first virologic failure.
Discussion: The K103 N/S mutation was documented in most genotypic sequences, due to the frequent use of EFV as the primary NNRTI in the first-line therapy for more than a decade in Brazil.
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 (G190S, K101E) and nucleoside reverse transcriptase inhibitors (NRTIs) (M184V).
Result: Four carried mutations towards NNRTI only (K103N and K103N/S) and one carried mutations to both NNRTI (G190S, K101E) and PMID: 29732898

Abstract: The most frequent WHO-defined DRMs were NRTI: codon T215 (3.0%), NNRTI: K103N/S (4%), and PI: L90 (1%
Result: Analysis of the three most prevalent NNRTI mutations is shown in Figure 6; the prevalence of the K103N/S mutation continued to increase until 2008 (6% in 2008) and then declined in prevalence in 2009 to 3%.
Result: The most prevalent NNRTI mutation was K103N/S with 4%, 95% CI: 3.7%-5.0%.
Result: The prevalence of NNRTI mutations was 6% [95% CI (5.5%-7.0%)], and the most prevalent NNRTI mutation was K103N/S [4%, 95% CI (3.7%-5.0%)].
Surveillance of HIV-1 pol transmitted drug resistance in acutely and recently infected antiretroviral drug-naive persons in rural western Kenya.
Abstract: Predominant TDR mutations in the reverse transcriptase included K103N/S (4.6%) and M184V (2.3%); only M46I/L (1.1%) occurred in the protease.
Result: The dominant TDRMs in the RT gene were K103N/S (n = 4, 4.6%) and M184V (n = 2, 2.3%), while in the PR gene only M46I/L (n = 1, 1.1%) occurred.
Table: K103S
Discussion: As reported from other studies, NNRTI mutations comprised a majority of the detected TDRMs, with K103N/S predominating.
Week 48 resistance analysis of Elvitegravir/Cobicistat/Emtricitabine/Tenofovir DF versus Atazanavir + Ritonavir + Emtricitabine/Tenofovir DF in HIV-1 infected women (WAVES study GS-US-236-0128).
