Reference compiled from: HGNC, Ensembl, NCBI, UniProt, PDB, AlphaFold, ClinVar, AlphaMissense, SpliceAI, Reactome, Gene Ontology, STRING, IntAct, BioGRID, ChEMBL, Bgee, HPO, GWAS Catalog, Orphanet, GenCC, PharmGKB I have compiled a comprehensive cross-database identifier and functional mapping reference for human IDH1 (Isocitrate dehydrogenase [NADP] cytoplasmic). This reference covers all 12 requested sections with data gathered from 70+ biological databases including: Key Highlights:

  • Gene: HGNC:5382 | ENSG00000138413 | Entrez 3417 | Chr 2q34 (208,236,224-208,266,095)
  • Protein: UniProt O75874 | 414 amino acids | 46.7 kDa
  • Structures: 60 PDB entries (including key R132H mutant structures) + AlphaFold (pLDDT 96%)
  • Clinical Variants: 489 ClinVar entries (including critical R132H somatic mutation)
  • AI Predictions: 1,517 SpliceAI + 2,765 AlphaMissense predictions
  • Approved Drugs: 4 FDA-approved IDH inhibitors (Ivosidenib, Vorasidenib, Olutasidenib, Enasidenib)
  • Clinical Trials: 51+ trials for Ivosidenib alone
  • Disease Links: Maffucci syndrome, Ollier disease, gliomas, AML
  • Expression: Ubiquitous (highest in adrenal, liver, reproductive tissues) The R132H mutation is particularly significant as a driver mutation in gliomas and acute myeloid leukemia, which has led to the development of multiple targeted therapies now in clinical use.
