FGFR3
a receptor tyrosine kinase of the highly-conserved FGFR family that binds fibroblast growth factor (FGF). Mutations are associated with thanatophoric dysplasia (TD), craniosynostosis Adelaide type, many craniosynostotic syndromes and bone malformations. Three splice-variant isoforms have been described. Activating point mutations cause dwarfism, including achondroplasia, hypochrondroplasia and thanatophoric dysplasia, and facial and other morphogenetic disorders, including Crouzon syndrome, craniosynostosis Adelaide type, San Diego skeletal displasia and Muenke syndrome. Translocations t(4;14) involving the IgH region are common in multiple myeloma and frequently involve FGFR3. Activated FGFR3 found in 30% of bladder cancers and several cervical cancers, but not in other tumors. Two mutations found in colorectal cancer.
