Ok et al. reported the study of 80 AML patients with IDH mutations, associated with IDH mutations at the time of the remission after induction therapy: About 40% of these patients had persistent IDH mutations, associated with an increased risk of relapse after one year of follow-up compared to patients without a detectable IDH1/IDH2 mutation (59% vs. 24%, respectively) [138]. The gene discussed is IDH2; the disease is acute myeloid leukemia.
