Abstract Background HIV-1 nucleoside reverse transcriptase inhibitors NRTIs have been used in the clinic for over twenty years. Interestingly the complete resistance pattern to this class has not been fully elucidated. Novel mutations in RT appearing during treatment failure are still being identified. To unravel the role of two of these newly identified changes E40F and K43E we investigated their effect on viral drug susceptibility and replicative capacity. Results A large database Quest Diagnostics database was analysed to determine the associations of the E40F and K43E changes with known resistance mutations. Both .
