Clinics and Pathology


a myeloproliferative disorder that is frequently associated with T cell, or less commonly, B-cell non Hodgkin lymphoma

Phenotype stem cell origin

may involve a stem cell involving both myeloid, T lineage, and B-cell lineage


14 cases are described; median age 43 yrs (range 18-68); sex ratio: 6M/8F


aggressive disease; complex picture of myeloid hyperplasia progressing to myelodysplasia and Tor -B- cell lymphoma; enlarged lymph node; blood data: high WBC (median 40 X 109/l); myelemia; monocytosis and eosinophilia


the disease transforms to AML, or occasionally ALL, in a median of 6 months


median survival: 12 months


Cytogenetics morphological

the same t(8;13) is found both in the bone marrow and in the lymph node, ruling out the hypothesis of a leukemoid reaction caused by a lymphoma; the multilineage involvement suggests the malignant transformation of a primitive hematopoietic stem cell.

Additional anomalies

usually occurs as a single anomaly; duplication of the der(13) was found during disease progression, suggesting that the crucial event might lie on this derivative chromosome; +8, +21 are also recurrently found

Genes Involved and Proteins

Gene name
FGFR1 (Fibroblast Growth Factor Receptor 1)
Gene name
ZMYM2 (fused in myeloproliferative disorders).
Protein description
zinc finger protein (ten repeats in the N-terminal region with the consensus sequence C-X2-C-X18-24-(F/Y)-C-X3-C that corresponds to a novel type of zing finger motifs), a hydrophobic repeat (proline-rich), and potentially two putative nuclear localisation signals

Result of the Chromosomal Anomaly

Atlas Image


breakpoint in FGFR1 intron 8Aberrant tyrosine kinase composed of the N-term two-thirds of FIM (retaining the 10 putative zinc finger motifs), and the FGFR1 intracellular region minus the major part of the juxtamembrane domain (and deleting the N-term immunoglobulin-like and central transmembrane domains of FGFR1)

Expression localisation



through constitutive activation of FGFR1 signal transduction pathways, possibly via dimerization capability mediated by the FIM N-term sequences of the fusion protein
