MARVEL on integrase mutations at position 97


HIVdb Algorithm: Comments & Scores
  • T97A is a polymorphic accessory INI-resistance mutation that, depending on subtype, occurs in 1% to 5% of viruses from untreated persons. It is selected by RAL and EVG. Alone, it has minimal if any effect on INI susceptibility but in combination with Y143C/R it markedly reduces RAL susceptibility.

Genotype-treatment correlation
Mutation frequency according to subtype and drug-class experience.
The frequency of each mutation at position 97 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.
