Clinics and Pathology
Disease
Described in only 3 cases, all of whom had a CML-like (chronic myelogenous leukemia-like) disease. Two had also had an excesss of B-lymphocytes in the marrow.
Phenotype stem cell origin
Involvement of both myeloid and lymphoid cells, so likely to be a stem cell. disorder
Evolution
At the time of writing, one patient had undergone myeloid transformation and a second patient underwent lymphoid transformation followed shortly by myeloid transformation. In common with other patients with FGFR1 fusion genes, the disease therefore appears to be aggressive.
Genes Involved and Proteins
Gene name
FGFR1 (Fibroblast Growth Factor Receptor 1)
Location
8p11.23
Protein description
Receptor tyrosine kinase for FGF ligands, also involved in the t(6;8)(q27;p12), t(8;9)(p12;q32-34) and t(8;13)(p12;q12)
Gene name
BCR (Breakpoint cluster region)
Location
22q11.23
Protein description
Normal function unclear; fuses to ABL in CML .
Result of the Chromosomal Anomaly
Description
5BCR - 3FGFR1
Transcript
All three patients has BCR exon 4 fused to FGFR1 exon 9
Detection protocole
RT-PCR or FISH
Description
Contains the coiled-coil domain of BCR, the BCR Y177 Grb2 binding site and the entire tyrosine kinase domain of FGFR1.
Oncogenesis
Analogous to BCR-ABL: constitutive activation of FGFR1 tyrosine kinase. Transforms Ba/F3 cells to IL-3 independence. Transformed cells are not affected by imatinib (Gleevec/Glivec/STI571) but are inhibited by compounds with anti-FGFR activity.
