Abstract: In 7 of 12 children, M184V appeared with one thymidine-analogue-associated mutation (TAM) as the first mutation, while the remaining 5 children had only TAMs appearing either individually (n = 2), or as TAMs 1 (M41L, L210W, and T215Y) and 2 (D67N, K70R, and K219Q/E/R) appearing together (n = 3).
HIV-1 subtype B protease and reverse transcriptase amino acid covariation.
Result: The mutations most commonly observed (sometimes transiently) after the detection of K65R included K20R (3 animals), M41L (3 animals), S68G/K/N (12 animals), K70H/N/T/Q (9 animals), W88S (6 animals), Y115F (9 animals), F116W (6 animals), V118I (3 animals), I178M (6 animals), L214F (11 animals), and K219Q/R/E/N/D/H/G (7 animals) (table 1).

No response to first-line tenofovir+lamivudine+efavirenz despite optimization according to baseline resistance testing: impact of resistant minority variants on efficacy of low genetic barrier drugs.
Abstract: Retrospective single genome sequencing of the baseline sample revealed the presence of minority viral variants with additional mutations: a mutation conferring resistance to lamivudine (M184IV), a thymidine associated mutation (K219R) and mutations possibly associated with non-nucleoside reverse transcriptase resistance (F227S, M230IV).
Drug-resistant HIV infection among drug-naive patients in Israel.
Abstract: RESULTS: Major drug resistance mutations (protease: L90M; reverse transcriptase: M41L, K103N, V106M, M184V, Y181S, G190A, L210W, T215Y/F, and K219R) were detected in 1 subject with A subtype, 3 with subtype B, and 9 with subtype C.
Phenotypic impact of HIV reverse transcriptase M184I/V mutations in combination with single thymidine analog mutations on nucleoside reverse transcriptase inhibitor resistance.
Abstract: Mutations known to be associated with reduced sensitivity to NRTI or NNRTI (V118I, E44D, K219R, T69A, and V75L) were found in a low prevalence (0.6-2.4%).
Broad nucleoside-analogue resistance implications for human immunodeficiency virus type 1 reverse-transcriptase mutations at codons 44 and 118.

Abstract: As expected, E44A/D and V118I mutations were strongly associated with M41L, D67N, L210W, and T215Y but also with other mutations, including K43E/N/Q, T69D, V75M, H208Y, R211K, and K219R.
Reduced antiretroviral drug susceptibility among patients with primary HIV infection.
Abstract: Population-based sequence analysis of these 3 samples identified multidrug-resistance mutations in reverse transcriptase (M184V, T215Y, K219K/R) and protease (L101/V, K20R, M361, M46I, G48V, L63P, A71T, V771, V82T, 184V, L90M) in the 2 latter patient samples, along with numerous polymorphisms.

Abstract: Rapid failure was surprisingly associated with baseline presence of protease gene mutation L90M (P=.04) in the absence of D30N and with RT mutations D67N (P<.01), K70R/S (P=.02), and K219Q/W/R/E (P<.01).
