IDH2mutated
IDH2mutated refers to a genetic alteration in the isocitrate dehydrogenase 2 (IDH2) gene. The IDH2 gene provides instructions for making an enzyme that plays a role in cellular metabolism, specifically in the citric acid cycle, which is involved in energy production. Mutations in IDH2 can lead to the production of an abnormal enzyme. This abnormal enzyme gains a new function, catalyzing the production of an oncometabolite called 2-hydroxyglutarate (2-HG). Elevated levels of 2-HG can disrupt normal cellular processes and contribute to the development of cancer. IDH2 mutations are particularly found in certain types of cancer, including acute myeloid leukemia (AML), gliomas (a type of brain tumor), and chondrosarcomas. The presence of an IDH2 mutation can have implications for prognosis and treatment strategies. Targeted therapies that inhibit the activity of mutant IDH2 enzymes or reduce 2-HG levels are being investigated and are increasingly used in clinical practice for certain IDH2-mutated cancers. Identifying IDH2 mutation status is an important part of cancer diagnosis and personalized medicine.
