Nucleoside reverse transcriptase inhibitors which act as a major component of highly active antiretroviral therapy regimens are widely used in treatment of Acquired Immune Deficiency Syndrome. However, the emergence of drug-resistant variants of HIV-1 severely limits the effectiveness of these drugs. Many drug resistance mutations confer a fitness cost, which can be partially overcome by compensatory mutations or other molecular mechanisms. This review focuses on the impacts of resistance mutations emerging during treatment with nucleoside reverse transcriptase inhibitors on viral fitness, and inter actions between these mutations.
