  The prevalence of transmitted HIV drug resistance among MSM in Anhui province, China.
 PMID: 25035709       2014       AIDS research and therapy
Result: T69A/N/S, V179E and P
Discussion: For example, L10V, V11I/V, L33F, T69A/N/S, and P236L were present only in individuals with CRF01_AE strains.
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.


  Cobicistat-boosted darunavir in HIV-1-infected adults: week 48 results of a Phase IIIb, open-label single-arm trial.
 PMID: 25926858       2014       AIDS research and 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).

  Molecular epidemiology of HIV in a cohort of men having sex with men from Istanbul.
 PMID: 23296905       2013       Medical microbiology and immunology
Abstract: In these patients, the nucleoside reverse transcriptase inhibitor (NRTI)-associated resistance mutations M41L, T215C, V75I, T69N, the non-NRTI associated mutations V106I, E138A, K103N and the protease inhibitor associated mutations Q58E and V82I were detected.


  Transmission patterns of HIV-subtypes A/AE versus B: inferring risk-behavior trends and treatment-efficacy limitations from viral genotypic data obtained prior to and during antiretroviral therapy.

  Transmitted HIV drug resistance in treatment-naive Romanian patients.
 PMID: 23592112       2013       Journal of medical virology
Result: Several atypical substitutions at key positions known to be linked with drug resistance were detected also within the RT gene: for NRTI-T69S (1/61 patients), T69N (2/61 patients) and for NNRTI-E138A/ G (5/61 patients), H221Y (1/61 patients).


  Clinical, virological and biochemical evidence supporting the association of HIV-1 reverse transcriptase polymorphism R284K and thymidine analogue resistance mutations M41L, L210W and T215Y in patients failing tenofovir/emtricitabine therapy.
 PMID: 22889300       2012       Retrovirology
Result: Interestingly, T69N appeared to be strongly correlated with K219Q (phi = 0.76, P = < 10-14) but also with K70R (phi = 0.50, P < 10-6).

  HIV-1 drug resistance genotyping from antiretroviral therapy (ART) naive and first-line treatment failures in Djiboutian patients.
 PMID: 23044036       2012       Diagnostic pathology
Result: The NRTI-associated mutations were D67N (2 strains), T69N (1), M184V (6), L210W (2), T215Y (2).
Table: T69N


  Herpes simplex virus type 2 suppressive therapy with acyclovir or valacyclovir does not select for specific HIV-1 resistance in HIV-1/HSV-2 dually infected persons.
 PMID: 21148504       2011       The Journal of infectious diseases
Introduction: Two other mutations (T69N and M184I) were also detected in a minority of sequences in these in vitro experiments.
Result: No cases of T69N or M
Discussion: The mutations selected in the in vitro experiments confer cross-resistance to NRTIs: V75I contributes resistance to multiple NRTIs in the presence of a concurrent Q151M mutation, T69N and other variants at position 69 are selected by didanosine and other NRTIs but their susceptibility profiles are not well-described (http://hivdb.stanford.edu/), and the variants M184I/V confer high-level resistance to lamivudine and emtricitabine.
