Clinics and Pathology

Disease Myeloid and lymphoid neoplasms with FGFR1 abnormalities (previously: 8p11 myeloproliferative syndrome)
Note Different disease phenotypes according to the FGFR1 partner gene.
Phenotype / cell stem origin Pluripotent haematopoietic stem cell.
Epidemiology Only one case to date, a 63 years old female with myeloproliferative/myelodysplastic neoplasm (Gervais et al., 2013).
Clinics Splenomegaly, dyspnea, impaired general condition at diagnosis. Rapid disease progression despite chemotherapy.
Bone marrow (MGG): hypercellularity with granular hyperplasia, dysgranulopoiesis and few eosinophils.
Evolution Disease progressed rapidly and the patient died 6 months after the diagnosis.
Prognosis Undetermined (myeloid and lymphoid neoplasms with FGFR1 abnormalities prognosis is currently poor).


Cytogenetics Morphological t(2;8)(q12;p11) without additional abnormality.
  R and G-banding showing t(2;8)(q12;p11).
  Cohybridization of FGFR1 BAC RP11-350N15 (8p11, green) and RANBP2 RP11-84C2 (2q12, red) showing a dual fusion signal.
