MARVEL on integrase mutations at position 157


HIVdb Algorithm: Comments & Scores
  • E157Q is a minimally polymorphic mutation that is selected in vitro by EVG (Jones et al. 2007; Shimura et al. 2007) and rarely in vivo by RAL (Malet et al. 2008). It appears to have minimal if any effect on INI susceptibility (Goethals et al. 2010; Reuman et al. 2010).

Genotype-treatment correlation
Mutation frequency according to subtype and drug-class experience.
The frequency of each mutation at position 157 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.
