Clinics and Pathology

Disease myeloide lineage
Phenotype / cell stem origin myeloproliferative/myelodysplastic syndrome (intermediate between CML and CMML) with eosinophilia; appear to be a specific entity
Epidemiology rarely described; mostly in adult male patients (13 of 14 cases herein reviewed)
Clinics organomegaly in 9 of 12 cases; blood data: median WBC: 40 X 109/l; numerous eosinophils: median 2.8 X 109/l, range 0.8-128 X 109/l, n=9 (normal range is 0.02-0.45 X 109/l), and, at times, of monocytes; no blast cells
Treatment hydroxyurea alone or polychemotherapy have been essayed
Prognosis yet partly undetermined; median survival < 20 mths (n= 11)

Cytogenetics

Additional anomalies +8

Genes involved and Proteins

Gene Name PDGFRB
Location 5q33
Protein PDGFRB is the receptor for PDGFB (platelet-derived growth factor-b); membrane protein; belongs to the immunoglobulin superfamily
Gene Name ETV6
Location 12p13
Dna / Rna 9 exons; alternate splicing
Protein contains a Helix-Loop-Helix and ETS DNA binding domains; wide expression; nuclear localisation; ETS-related transcription factor

Result of the chromosomal anomaly

Hybrid gene
Description 5' ETV6 - 3' PDGFRB
  
Fusion Protein
Description N-term HLH domain of ETV6 fused to the transmembrane domain and the Tyr kinase domain of PDGFRb in C-term; the reciprocal transcript is not expressed
