Clinics and Pathology

Disease Acute monoblastic leukaemia (AML-M5a)
Epidemiology Poorly defined, only one case described to date, a 15 years-old boy with AML-M5a relapse (Zerkalenkova et al., 2018).
Treatment The patient was treated according to AML-BFM-2004 protocol and remission was achieved after the 2nd induction course. After two years a bone marrow relapse of AML M5a was diagnosed.
Prognosis The prognosis was poor, the current patient died due to the progression of the disease (Zerkalenkova et al., 2018).


  The probe was hybridized to metaphase and displayed 3'-portion of KMT2A translocated to chromosome 16 (Zerkalenkova et al., 2018).
Probes MLL dual color break apart rearrangement probe.

Genes involved and Proteins

Gene NameKMT2A (lysine (K)-specific methyltransferase 2A)
Location 11q23.3
Dna / Rna KMT2A gene consists of 37 exons encoding a 3969 amino-acid nuclear protein with a molecular weight of nearly 431 kDa.
Protein 431 kDa; contains two DNA binding motifs (a AT hook and Zinc fingers), and a DNA methyl transferase motif; wide expression; nuclear localization; transcriptional regulatory factor.
Gene NameUSP10 (ubiquitin specific peptidase 10)
Location 16q24.1
Dna / Rna USP10 gene consists of 14 exons encoding a 798 amino-acid protein with a molecular weight of 87134 Da.
Protein 87134 Da; belongs to the ubiquitin-specific proteases family; contains N-terminal thiol hydrolase catalytic domain and C-terminal Ataxin-2 extension that mediates protein-protein interactions; widely expressed; found in nucleus, cytoplasm and early endosomes; deubiquitinates various substrates. Main substrate: TP53. Upon DNA damage USP10 moves to nucleus where deubiquitinates the p53 protein thus increasing p53 levels (Yuan et al., 2010).

Result of the chromosomal anomaly

Hybrid gene
Note KMT2A/USP10 fusion gene was detected by LDI-PCR (Zerkalenkova et al., 2018).
  Upper line: KMT2A/USP10 fusion gene sequence. Lower line: KMT2A/USP10 fusion transcript RT-PCR and Sanger sequencing.
Description KMT2A/USP10 fusion gene contains 5'-portion of KMT2A and 3'-portion of USP10. Breakpoints are localized in KMT2A intron 12 and USP10 intron 1.
Fusion Protein
Description KMT2A/USP10 fusion protein joins amino-acid residue 1493 of KMT2A to amino-acid residue 8 of USP10 thus retaining KMT2A AT hooks, Pro-rich, and the Zn finger CXXC type domains and almost entire USP10.
