Mutation of either IDH1 or IDH2 imparts a "neomorphic enzymatic activity" on the encoded enzymes, resulting in the gain-of-function ability to convert alpha-ketoglutarate (α-KG) into the oncometabolite 2-hydroxyglutarate (2-HG), while simultaneously converting NADPH to NADP+.
Abbreviations: 2-HG, 2-hydroxyglutarate; α-KG, alpha-ketoglutarate; IDH, isocitrate dehydrogenase; NADP+/NADPH nicotinamide adenine dinucleotide phosphate; PDH, pyruvate dehydrogenase.
