Gene Description | DNMT3A, DNA methyltransferase 3 alpha, mediates DNA methylation and functions in modification of gene expression, and plays a role in hematopoietic differentiation (PMID: 28286768, PMID: 25693834). DNMT3A mutations are frequent in acute myeloid leukemia, and are recurrent in myelodysplastic syndromes (PMID: 28286768, PMID: 28003281). | ||||||||||
