OnCo

TET2 is an enzyme that helps erase methyl marks from DNA so genes can be switched back on. Losing it is one of the commonest first steps toward blood cancer; mutant IDH blocks it indirectly, which is part of how ivosidenib works when it restores normal maturation. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Mutant IDH1 converts alpha-ketoglutarate to the oncometabolite 2-hydroxyglutarate, TET2 and histone demethylases lose activity, and blasts stop maturing; ivosidenib shuts off 2-HG production and TET2 regains activity (ivosidenib mechanism steps). TET2 itself has no drug in the corpus.

Where it is found
  • Clonal haematopoiesis of indeterminate potential
  • IDH-mutant AML (TET2 inhibited by 2-hydroxyglutarate)
  • Follicular helper T-cell lymphomas with TET2 and DNMT3A mutations
