IDH2 R140Q IDH2 I319M | acute myeloid leukemia | resistant | Enasidenib | Case Reports/Case Series | Actionable | In a clinical case study, IDH2 I319M was identified as an acquired mutation in a patient with acute myeloid leukemia harboring IDH2 R140Q upon progression on Idhifa (enasidenib) (PMID: 36222845). | 36222845 |
IDH2 R140Q IDH2 I319M | acute myeloid leukemia | resistant | Enasidenib | Case Reports/Case Series | Actionable | In a clinical study, IDH2 I319M 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 I319M in trans or in cis with IDH2 R140Q conferred resistance to Idhifa (enasidenib) in culture, supporting a mechanism of variants cooperating to confer resistance (PMID: 29950729). | 29950729 |
