Genes affected

DOT1L (HGNC:24948): (DOT1 like histone lysine methyltransferase) The protein encoded by this gene is a histone methyltransferase that methylates lysine-79 of histone H3. It is inactive against free core histones, but shows significant histone methyltransferase activity against nucleosomes. [provided by RefSeq, Aug 2011]

The c.1433C>T (p.A478V) alteration is located in exon 15 (coding exon 15) of the DOT1L gene. This alteration results from a C to T substitution at nucleotide position 1433, causing the alanine (A) at amino acid position 478 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
