Clinics and Pathology



Phenotype stem cell origin

M5/M4; ALL at times, therapy related cases


from infants to adults




Cytogenetics morphological

A high diversity of reported breakpoints onchromosome 10, from 10p11 to 10p15: remains to be fully studiedL

Additional anomalies

inv(11)(q13q23) is frequently acompanying thet(10;11); this is likely to be related to the transcription directions ofthe two genes

Genes Involved and Proteins

Gene name
MLLT10 (myeloid/lymphoid or mixed-lineage leukemia (trithorax homolog, Drosophila); translocated to, 10)
Dna rna description
5 telomeric --> 3 centromeric orientation
Protein description
contains 3 Zn fingezrs and a leucine zipper; nuclearlocalisation; transcription factor
Gene name
KMT2A (myeloid/lymphoid or mixed lineage leukemia)
Dna rna description
21 exons, spanning over 100 kb; 13-15 kb mRNA
Protein description
431 kDa; contains two DNA binding motifs (a AT hook,
Protein description
and Zinc fingers), a DNA methyl transferase motif, a bromodomain;
Protein description
transcriptional regulatory factor; nuclear localisation

Result of the Chromosomal Anomaly


5 MLL - 3 AF10; variable breakpoints on both chromosomes; thefusion transcript on chromosome 11 is the crucial one; MLL and AF10 are inopposite transcriptional directions, wich may be cause of the complexity ofthe translocationN-term AT hook and DNA methyltransferase from MLL fused to theleucine zipper C-term of AF10

Expression localisation

nuclear localisation
