NCIt related terms : MLL Partial Tandem Duplication;
NCIt definition : A chromosomal rearrangement where exons 5 through 11 or 5 through 12 of the MLL gene
are duplicated and inserted upstream of exon 4 of the gene. This duplication results
in transcripts and proteins that have the N-terminal region, which contains the AT
hook DNA-binding motifs, and the transcriptional repression domain duplicated. This
mutation is associated with myelodysplastic syndrome (MDS) and susceptibility of MDS
progression to acute myeloid leukemia.;
