1. Identity

ICD-Morpho 9989/3 Myelodysplastic syndrome, unclassifiable
Atlas_Id 1226

2. Clinics and Pathology

Disease Myelodysplastic syndrome
Epidemiology only one case to date
Clinics a 36 yr old female patient
Cytology eosinophilia
Evolution progressed to overt leukemia with megakaryocytic blasts

3. Cytogenetics

Additional anomalies complex karyotype

4. Genes involved and Proteins

Gene NameSYK (spleen tyrosine kinase)
Location 9q22.2
Protein contains SH2 domains and a protein kinase domain; non-receptor type protein-tyrosine kinase; role in signaling pathways
Gene NameETV6 (ets variant 6)
Location 12p13.2
Protein contains a Helix-Loop-Helix and ETS DNA binding domains; wide expression; nuclear localisation; ETS-related transcription factor

5. Result of the chromosomal anomaly

Hybrid gene
Description 5' ETV6 - 3' SYK; the counterpart SYK-ETV6 is also expressed
Fusion Protein
Description N term ETV6 exons 1 to 5 (with the Helix-Loop-Helix domain), fused to the C term SYK, containing the protein kinase domain
Oncogenesis ETV6-SYK is constituvely tyrosine phosphorylated

6. To be noted

Additional cases are needed to delineate the epidemiology of this rare entity:
