myeloid leukemia of acute myeloid leukemia (AML) M5a showing a jumping translocation with a breakpoint at 11q23. Fluorescence in situ hybridization (FISH) demonstrated triplication of the MLL gene and the presence of interstitial telomeric sequences, supporting the role of repetitive sequences in the mechanism of jumping translocations. Southern blot analysis of the MLL breakpoint cluster region showed the presence of an MLL gene rearrangement. Jumping translocation with MLL gene rearrangement is a previously unreported phenomenon in leukemia cytogenetics.

Protein Lysine Methyltransferase,Protein Methylase III,Protein Methyltransferase III,Histone-Lysine Methyltransferase,Histone Lysine Methyltransferase,Histone Lysine N Methyltransferase,Methyltransferase, Histone-Lysine,Methyltransferase, Protein Lysine,N-Methyltransferase, Histone-Lysine
D011519 Proto-Oncogenes Normal cellular genes homologous to viral oncogenes. The products of proto-oncogenes are important regulators of biological processes and appear to be involved in the events that serve to maintain the ordered procession through the cell cycle. Proto-oncogenes have names of the form c-onc. Proto-Oncogene,Proto Oncogene,Proto Oncogenes
