Biochem/physiol Actions

D-(or R-) enantiomer of α-hydroxyglutaric acid is a cancer related biomarker of diagnostic value, whereas the L-(or S-) enantiomer of α-hydroxyglutaric acid is a biomarker for certain neurometabolic, inherited disorder diseases. It has no known physiological function in eukaryotes. It is toxic to the brain and increases the susceptibility to develop brain tumors.

The arginine 132 (R132) mutation of isocitrate dehydrogenase -1 (IDH1(R132)) results in production of 2-hydroxyglutarate (2-HG) and is associated with a better prognosis compared with wild-type (WT) in glioma patients. The majority of lower-grade gliomas express IDH1(R132), whereas this mutation

A number of human cancers harbor somatic point mutations in the genes encoding isocitrate dehydrogenases 1 and 2 (IDH1 and IDH2). These mutations alter residues in the enzyme active sites and confer a gain-of-function in cancer cells, resulting in the
