DNMT3A (Q9Y6K1) variants and mutations

DNMT3A (also known as Q9Y6K1) is a human protein-coding gene encoding a DNA (cytosine-5)-methyltransferase 3A protein. It establishes new DNA methylation patterns during development and hematopoietic differentiation. Somatic variants are common in clonal hematopoiesis and acute myeloid leukemia, while germline variants cause Tatton-Brown-Rahman overgrowth syndrome. This analysis covers 2,408 DNMT3A variants and mutations. Of these, 75% have computational variant effect predictions. Disease context includes acute myeloid leukemia, Tatton-Brown-Rahman overgrowth syndrome, and Heyn-Sproul-Jackson syndrome. Example DNMT3A variants include P2L, P2S, and A3D.
