Result: The identified NRTI mutations included D67N and K65R, while the NNRTI mutations were V106M and Y181C.

Emergence of drug resistance in human immunodeficiency virus type 1 infected patients from pune, India, at the end of 12 months of first line antiretroviral therapy initiation.
Discussion: The type I pattern includes the mutations M41L, L210W, and T215Y while type II pattern includes D67N, K70R, T215F, and K219Q/E.
Discussion: Type I TAMs were seen in 2 study sequences in our study out of which in 1 study sequence all the three type I TAMs were seen along with D67N.

Introduction: There are two TAM pathways: type I (M41L, L210W and T215Y) and type II (D67N, K70R, T215F and K219Q/E); the former conferring higher levels of resistance and cross-resistance.
Result: A total of 35 patients had at least 1 TAM, with the following distribution: M41L (16%), D67N (15%), K70R (9%), L210W (11%), T215Y (16%), T215F (11%), K219Q (5%) and K219E (2%).
Virological failure and HIV-1 drug resistance mutations among naive and antiretroviral pre-treated patients entering the ESTHER program of Calmette Hospital in Cambodia.
Abstract: The nucleotide position of A2723G, A2747G and C2750T were frequent polymorphisms for the wild-type amino acids K65, K66 and D67, respectively, and 14 specimens had the D67N mutation encoded by G2748A.
Result: Fourteen specimens had a G2748A mutation that led to D67N, a thymidine analogue mutation.

The lysine 65 residue in HIV-1 reverse transcriptase function and in nucleoside analog drug resistance.
Introduction: Several mutations (the thymidine analog mutations, TAM) are required for high-level AZT resistance by excision, and include M41L, D67N, K70R, T215F or Y and K219E or Q.

Abstract: However, thymidine analogue resistance mutations (TAMs) determined two distinct genotypic profiles in the HIV-1 reverse transcriptase: TAM1: M41L, L210W and T215Y, and TAM2: D67N, K70R, K219E/Q, and T215F.

Persistence of frequently transmitted drug-resistant HIV-1 variants can be explained by high viral replication capacity.
Result: It showed that M41L, D67N, T69D, K70R, and K219R were the most common NRTI mutations that associated with the three NNRTI mutations, K103N, Y181C and G190A.
