DNA methyltransferase 3A (DNMT3A)

Short target page →

DNMT3A writes new methyl marks on DNA; it is one of the most commonly mutated genes in acute myeloid leukaemia and is trapped by the hypomethylating drugs azacitidine and decitabine. 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

A de novo methyltransferase working with DNMT3L during development and in haematopoietic stem cells; the R882H mutant acts dominantly to reduce methylation.

Where it is found
  • Haematopoietic stem cells
  • Mutated in a large share of AML and in clonal haematopoiesis
