Result: The M41L, D67N, V118I, L210W, K219Q, and T69D mutations were more prevalent in experienced patients.
Result: The most prevalent mutations related to NRTIs were M184V (80.1%), followed by M41L (31.8%), T215Y (30.2%), D67N (25.5%), K70R (24.4%), T215F (18.3%), L210W (15.1%), and V118I (15.1%) (Figure 1(a)).
HIV Drug Resistance Surveillance in Honduras after a Decade of Widespread Antiretroviral Therapy.
Result: N[t]RTI RAMs were found in 14% of patients (43/313; 36 and seven patients), most commonly V118I (6%; 18/313; 18 and zero patients), T69D/N (3%; 8/313; eight and zero patients) and M184V/I (3%; 8/313; two and six patients).
Horizontal gene transfer from human host to HIV-1 reverse transcriptase confers drug resistance and partly compensates for replication deficits.
Discussion: Although reverse transcriptase changes associated with the E44D and V118I mutations may have an accessory role in increased resistance to nRTIs in the presence of TAMs, their clinical relevance is very limited.
Persistence of frequently transmitted drug-resistant HIV-1 variants can be explained by high viral replication capacity.

Abstract: Single mutations E138K (two cases) and M184V in three distinct patients and V90I+G190E; M184V+A98S; Y215F+V118I+T215I; L210S+T215I+F227L; and A62V+D67G+K70N+188H in the remaining five subjects.

Abstract: Codon changes K43E, E44D and V118I were found to have no effect on susceptibility to three NRTIs with or without TAMs in either subtype; however, some accessory mutations had subtype-specific effects on viral infectivity.
