IDH1 (isocitrate dehydrogenase 1 (NADP+), soluble) encodes for the isocitrate dehydrogenase [NADP] cytoplasmic protein, an epigenetic modifier. IDH1 is frequently mutated in glioma and acute myeloid leukemia, among other cancer types (PMID: 23558169).


IDH1 is altered in 3.06% of all cancers with malignant glioma, oligodendroglioma, astrocytoma, leukemia, and bile duct carcinoma having the greatest prevalence of alterations [3].

The most common alterations in IDH1 are IDH1 Mutation (3.98%), IDH1 Codon 132 Missense (3.18%), IDH1 R132H (1.97%), IDH1 R132C (0.82%), and IDH1 R132L (0.14%) [3].
