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]
