Genes affected

MLLT10 (HGNC:16063): (MLLT10 histone lysine methyltransferase DOT1L cofactor) This gene encodes a transcription factor and has been identified as a partner gene involved in several chromosomal rearrangements resulting in various leukemias. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2010]
