Research on the treatment effects and drug resistances of long-term second-line antiretroviral therapy among HIV-infected patients from Henan Province in China.
Result: TAM (M41 L, K70R, L210 W, and T215F) and D67N mutations, associated with resistance to TDF, were detected during second-line ART.
Table: D67N
Discussion: TDF was used in the second-line program; the mutations associated with resistance to TDF were K65R, TAM (M41 L, K70R, L210 W, T215F), D67N, K70E, and Y115F.
Discussion: The D67N mutation, present with other TAMs, can result in reduced susceptibility to TDF.
Characterization of minority HIV-1 drug resistant variants in the United Kingdom following the verification of a deep sequencing-based HIV-1 genotyping and tropism assay.
Result: Most of the minority mutations in viruses from both groups of naive patients were observed in the RT, e.g., M41L, E44D, A62V, K65R, D67N, D67G, V75I, L100I, K103N, K103R, V188I, M184I, L210W, K219Q, Y318F, etc., although a number of minority mutations associated with resistance to PI (L10F, V11I, M46I/
Increasing proportions of HIV-1 non-B subtypes and of NNRTI resistance between 2013 and 2016 in Germany: Results from the national molecular surveillance of new HIV-diagnoses.
Discussion: Generally, it is known that mutations selected by TAMS confer resistance to internationally approved NRTIs; examples of such TAMS encountered in the study are M41 L, D67N, K70R, L210 W, T215Y/F and K219Q/E.

Abstract: However, the detection of RAMs by UDS with a 1% cut-off was significantly higher than that of bulk sequencing for RT codons D67N (65.4% versus 52.3%), M184V (66.2% versus 52.3%), L210W (48.9% versus 36.4%) and T215Y (57.9% versus 42.1%) and PR codons M46I (46% versus 26%), I54L (12.4% versus 3.9%), V82A (44.5% versus 29.9%) and L90M (57.7% versus 42.5%).

Result: Other mutations such as T215F/Y and D67N/E were also more prevalent in mothers (16.67% and 11.11% respectively) than in infants (5.56% and 5.56% respectively) (Table 3).
Result: The drugs affected by these mutations were AZT (T215F/Y, D67N/E); 3TC (M184V, T215F/Y, D67N/E), FTC (M184V), ABC (M184V) and TDF (T215F/Y).
Discussion: Others mutations detected such as T215F/Y, D67N/E, K70R, and K219Q are associated with intermediate resistance to

Abstract: Major NRTI mutations were detected in 11 patient samples, which included M184V (n = 6), M41L (n=3), D67N (n=2), K219Q (n=3) and T215F (n=2).

HIV-1 transmission networks across Cyprus (2010-2012).
Result: The second study subject, also a Romanian citizen living in Cyprus, was also infected with a sub-subtype F1strain dual-class RT and PI resistant strain carrying D67N, K70R, M184V, T215F, Y181C, M46L, I54V and V82F mutations associated with drug resistance.
