FGFR1(redirected from Basic Fibroblast Growth Factor Receptor 1)
Also found in: Acronyms.
FGFR1A gene on chromosome 8p12 that encodes fibroblast growth factor receptor-1, which has an extracellular region composed of 3 immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. Binding of a ligand unleashes a cascade of downstream signals that impact on mitogenesis and differentiation.
FGFR1 mutations are associated with inherited syndromes (e.g., Antley-Bixler syndrome, autosomal dominant Kallmann syndrome 2, Jackson-Weiss syndrome, osteoglophonic dysplasia and Pfeiffer syndrome), as well as myeloproliferative disorders and stem cell leukaemia lymphoma syndrome.
