Disease

IDHP_HUMAN D-2-hydroxyglutaric aciduria. Defects in IDH2 are the cause of D-2-hydroxyglutaric aciduria type 2 (D2HGA2) [MIM:613657. D2HGA2 is a neurometabolic disorder causing developmental delay, epilepsy, hypotonia, and dysmorphic features. Both a mild and a severe phenotype exist. The severe phenotype is homogeneous and is characterized by early infantile-onset epileptic encephalopathy and cardiomyopathy. The mild phenotype has a more variable clinical presentation. Diagnosis is based on the presence of an excess of D-2-hydroxyglutaric acid in the urine.^[1]

Function

IDHP_HUMAN Plays a role in intermediary metabolism and energy production. It may tightly associate or interact with the pyruvate dehydrogenase complex.

Publication Abstract from PubMed

Somatic gain-of-function mutations in isocitrate dehydrogenase (IDH) 1 and 2 are found in multiple hematologic and solid tumors, leading to accumulation of the oncometabolite, (R)-2-hydroxyglutarate (2HG). 2HG competitively inhibits alpha-ketoglutarate-dependent dioxygenases, including histone demethylases and methylcytosine dioxygenases of the Tet family, causing epigenetic dysregulation and a block in cellular differentiation. In vitro studies have provided proof of concept for mutant IDH inhibition as a therapeutic approach. We report the discovery and characterization of AG-221, an orally available, selective, potent inhibitor of the mutant IDH2 enzyme. AG-221 suppressed 2HG production and induced cellular differentiation in primary human IDH2 mutation-positive acute myeloid leukemia (AML) cells ex vivo and in xenograft mouse models. AG-221 also provided a statistically significant survival benefit in an aggressive IDH2R140Q-mutant AML xenograft mouse model. These findings supported initiation of the ongoing clinical trials of AG-221 in patients with IDH2 mutation-positive advanced hematologic malignancies.
