Activating mutations in FGFR3 that introduce a mutant cysteine residue to the Ig2-Ig3 linker domain or the extracellular juxtamembrane region have been identified in the lethal neonatal disorder thanatophoric dysplasia (Tavormina, 1995a, b; Rousseau, 1996; reviewed in Webster and Donoghue, 1997; Burke, 1998). The presence of the mutant cysteine residue causes ligand-independent dimerization of the receptor through Cys-mediated intramolecular disulphide bonds and leads to increased biological signaling without changing the intrinsic kinase activity of the receptor (d'Avis, 1998; Adar, 2002). More recently, the same mutations, arising somatically, have been identified in a range of cancers including bladder, prostrate and cervical cancer, as well as in multiple myeloma and head and neck squamous cell carcinoma (reviewed in Wesche, 2011).
