MARVEL on integrase mutations at position 263


HIVdb Algorithm: Comments & Scores
  • R263K is a nonpolymorphic mutation selected in patients receiving RAL and DTG and in vitro by EVG and DTG. It reduces RAL, DTG, and EVG susceptibility about 2-fold, 2-fold, and 3 to 5-fold, respectively.

Footnote:Mutation scores on the left are derived from published literature linking mutations and ARVs (the complete details can be found in the HIVdb Release Notes).
Genotype-treatment correlation
Mutation frequency according to subtype and drug-class experience.
The frequency of each mutation at position 263 according to subtype and drug-class experience. Data are shown for the 8 most common subtypes. The number of persons in each subtype/treatment category is shown beneath the subtype. Mutations occurring at a frequency >0.5% are shown. Each mutation is also a hyper-link to a separate web page with information on each isolate, including literature references with PubMed abstracts, the GenBank accession number, and complete sequence and treatment records.
