Result: One patient (patient 14 in Table 4) showed the transient development of the N[t]RTI RAM L74I/L and the NNRTI RAM P225H/P at the Week 16 visit, which were not detected at the subsequent Week 48 visit analysis as shown in Table 4.

Abstract: The concordance rates between the RFMP and direct sequencing assays for the examined codons were 97% (K65R), 97% (T69Ins/D), 97% (L74VI), 97% (K103N), 96% (V106AM), 97% (Q151M), 97% (Y181C), 97% (M184VI) and 94% (T215YF) in the reverse transcriptase coding region, and 100% (D30N), 100% (M46I), 100% (G48V), 100% (I50V), 100% (I54LS), 99% (V82A), 99% (I84V) and 100% (L90M) in th
Prevalence of HIV-1 drug resistance among women screening for HIV prevention trials in KwaZulu-Natal, South Africa (MTN-009).
Abstract: Major mutations in reverse transcriptase included K65R(n = 1), L74I(n = 1), K103N(n = 19), V106M(n = 4), Y181C(n = 2), M184V(n = 4), and K219E/R(n = 2).
Result: The following mutations were detected in only one sample each: M46L and I85V (protease); K65R, L74I, K219E/R, and K101E (reverse transcriptase) (Figure 4).

Result: M184V, the 3TC-selected mutation was identified in three HIV resistant strains, alone in two cases and together with all the above mentioned type II TAMs, as well as other NRTI conferring resistance mutations (T69D and L74I) in one case.
Trends in Genotypic HIV-1 Antiretroviral Resistance between 2006 and 2012 in South African Patients Receiving First- and Second-Line Antiretroviral Treatment Regimens.
Method: Different RT mutations at the same residue were pooled, including the NRTI-resistance mutations D67NG, K70EGQ, L74VI, M184VI, T215YF, K219QE and the NNRTI-resistance mutations K101EH, K103NS, Y188LCH, and G190ASEQ.
Result: L74VI occurred in 13/153 (8.5%) patients receiving TDF and 30/54 (55.6%) receiving ABC compared with 1.8% receiving d4T or AZT (p<0.001 for both TDF and ABC).
Result: Three mutatio
