Relevant Treatment Approaches


  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"


  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

IDH2 R140Q IDH2 Q316E acute myeloid leukemia resistant Enasidenib Case Reports/Case Series Actionable In a clinical study, IDH2 Q316E was identified as an acquired mutation in trans with the original IDH2 R140Q in a patient with acute myeloid leukemia (AML), who developed resistance to Idhifa (enasidenib) after initial response, and coexpression of IDH2 Q316E in trans or in cis with IDH2 R140Q conferred resistance to Idhifa (enasidenib) in culture and in animal models of AML, supporting a mechanism of variants cooperating to confer resistance (PMID: 29950729). 29950729
