Synonymous Genetic Polymorphisms within Brazilian Human Immunodeficiency Virus Type 1 Subtypes May Influence Mutational Routes to Drug Resistance
Background. 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 potentia...

| description | Background. 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. Methods. We investigated the nucleotide sequences at drug resistance-related sites, for all major Brazilian subtypes (B, C, and F1) of human immunodeficiency virus type 1 (HIV-1) group M. Results. We identified a change at positions 151 and 210 of the reverse-transcriptase region in subtype F1, such that the emergence of these key nucleoside/nucleotide analogue resistance mutations required an extra nucleotide change in subtype F1, compared with subtypes B and C. The clinical significance of position 210 was confirmed within a large Brazilian database, in which we identified a lower prevalence of the L210W mutation in subtype F1 virus, compared with subtype B virus, in patients matched for thymidine-analogue experience. An inverse relationship between the L210W and K70R mutations was also observed. Conclusions. The findings of the present study illustrate an important mechanism by which a subtype may determine genetic routes to resistance, with implications for treatment strategies for populations infected with HIV-1 subtype F. |
