Abstract: M184 V/I (26.14%), T69S (11.36%), and T215Y/I (10.23%) mutations were the most common in nucleoside reverse transcriptase inhibitors (NRTIs), and K103 N/R/S (21.59%), V179D/E (20.45%) in Non-NRTIs (NNRTIs).
Result: The most common NRTIs mutations were M184 V/I, T69S, and T215Y/I, with DR rates of 37.7, 16.39, and 14.75%, respectively.

Result: Mutations conferring NRTI resistance included K70R in 2 of 26 (7%) patients and T69S which was detected in 1 of 26 (3%) patients.
A post-partum single-dose TDF/FTC tail does not prevent the selection of NNRTI resistance in women receiving pre-partum ZDV and intrapartum single-dose nevirapine to prevent mother-to- child HIV-1 transmission.
Result: T69S, a mutation which confers resistance to all NRTI's was found in one patient.

Result: The prevalence for T69NS, V90I, and V106I was 1.5%, respectively.
Result: We also detected NRTI selected mutations M41L, E44D, T69ANS, V75M, and V118I, and NNRTI mutations V90I, A98G, K101EQ, K103NR, V106I, V108I, E138A, V179EI, and G190A (Table 3).
Prevention of mother-to-child HIV-1 transmission in Burkina Faso: evaluation of vertical transmission by PCR, molecular characterization of subtypes and determination of antiretroviral drugs resistance.
Discussion: The 69 insertion complex consists of a substitution at codon 69 (typically T69S) and an insertion of 2 or more amino acids (S-S, S-A, S-G, or others).
Characteristics of HIV-1 natural drug resistance-associated mutations in former paid blood donors in Henan Province, China.
Result: T69A/N/S, V179E and P236L were polymorphism mutations against RTIs.
Discussion: For example, L10V, V11I/V, L33F, T69A/N/S, and
Discussion: Other commonly observed mutations were T69A/N/S, V179E, L10I/L/V, V11I/V, L33F, and A71A/T/V; none of these mutations is known to confer drug resistance to NRTIs, NNRTIs, or PIs.
