Clinics and Pathology

Phenotype stem cell origin

Patients with EMS present with a myeloproliferative syndrome (MPS) with eosinophilia and a T-cell non Hodgkin lymphoma (NHL).


Only one case to date, a 75 year old female patient (Sohal et al., 2001; Hidalgo-Curtis et al., 2008).


The patient died 2 months after diagnosis, due to her lymphoma.

Genes Involved and Proteins

Gene name
FGFR1 (Fibroblast Growth Factor Receptor 1)
Protein description
Receptor tyrosine kinase; contains an extracellular ligand-binding domain with Ig-like structures, a transmembrane domain, and a cytosolic tyrosine kinase (TK) domain. Involved in signal transduction.
Gene name
CPSF6 (cleavage and polyadenylation specific factor 6)
Protein description
Contains a RNA recognition motif (RRM), a proline rich domain, and an arginine rich domain. Involved in pre-mRNA processing.

Result of the Chromosomal Anomaly


5 CPSF6-3 FGFR1; fusion of CPSF6 intron 8 to FGFR1 exon 9, at nucleotide 1272 from ATG.895 amino acids protein (97 kDa) with the RRM domain of CPSF6, fused to the TK domain of FGFR1.
