Most published data on antiretroviral-drug resistance is generated from in vitro or in vivo studies of subtype B virus. However, this subtype is associated with <10% of HIV infections worldwide, and it is essential to explore subtype-specific determinants of drug resistance. One potential cause of the differences between subtypes is the synonymous codon usage at key resistance positions.
