Journal of acquired immune deficiency syndromes (1999)
Abstract: Several discrete clusters involving transmission of K103N- and/or M41L-resistant virus to multiple recipients were detected, suggesting that multiple transmission pathways can exist for viruses with the same resistance mutations.
Analysis of nevirapine (NVP) resistance in Ugandan infants who were HIV infected despite receiving single-Dose (SD) NVP versus SD NVP plus daily NVP up to 6 weeks of age to prevent HIV vertical transmission.

Abstract: METHODS: We tested plasma HIV by using a genotyping assay (ViroSeq; Celera Diagnostics), a phenotypic resistance assay (PhenoSense; Monogram Biosciences), and sensitive point mutation assay (LigAmp, for K103N, Y181C, and G190A).
Method: PCR products generated in the ViroSeq system were also analyzed using the LigAmp assay to detect and quantify HIV variants with NVP resistance mutations (K103N=AAC, 0.5% assay cutoff; Y181C=TGT, 1% assay cutoff; G190A=GCA, 0.5% assay cutoff).

Abstract: The most common mutations conferring resistance to NNRTIs were K103N, Y181C and G190A, representing 56.5, 30.4 and 14.5%, respectively.

Abstract: K101E and G190S together tend to decrease susceptibility to all nucleoside RT inhibitors, but the K103N mutation had little effect on nucleoside RT inhibitor susceptibility.
Optimization of 5-aryloxyimidazole non-nucleoside reverse transcriptase inhibitors.
Abstract: Herein we present the optimization of a series of 5-aryloxy imidazoles, which possess a balanced pharmacological profile against both wild-type enzyme and the clinically relevant mutations K103N and Y181C.

Abstract: In the group of NRTI mutations M184V (26/75; 34.6%), A62V (12/75; 16.0%) and T215Y (8/75; 10.6%), in NNRTI mutations K103N (10/75; 13.3%), G190S (6/75; 8.0%), in PI group mutations L90M (6/75; 8.0%) and M461/L (6/75; 8.0%) occurred most frequently.

Abstract: Mutation K103N was observed in 56% (14/25) of the children while mutation T215Y was found in none.
Abstract: Mutations T215Y and K103N were detected by a nested cum amplification refractory mutation system polymerase chain reaction (ARMS PCR) and the results were confirmed by direct sequencing in five randomly selected cases.
Abstract: Two of the six drug naive children also showed K103N mutation.
