This splicing event leads to the generation of an mRNA encoding an FGFR3 protein in which the C-terminal portion of the Ig-like-3 domain and the transmembrane domain are deleted, while the remainder of the mature molecule is fused in-frame to the C-terminal cytoplasmic kinase domains.

A common mutation in the fibroblast growth factor receptor 1 gene in Pfeiffer syndrome. Deafness due to pro250-to-arg mutation of FGFR3. 60: 555-564, 1997. Fibroblast growth factor receptor 3 (FGFR3) mutations in sporadic cases of achondroplasia occur exclusively on the paternally derived chromosome. FGFR3-TACC3 activates oxidative phosphorylation and mitochondrial biogenesis and induces sensitivity to inhibitors of oxidative metabolism. Additional factors may present in the form of winging of the scapula, scoliosis, breast bone prominence (pectus carinatum), breast bone depression (pectus excavatum). J. Med. (2013) concluded that FGFR3 is a high-affinity receptor for botulinum neurotoxin A, which uses the same regions of FGFR3 as native ligands and induces FGFR3 phosphorylation. Severe kyphoscoliosis required surgical correction at age 7 years, which was complicated by postoperative lower limb paralysis requiring decompressive surgery.

Clinical and genetic analysis of patients Molec. At least two mutations in the TWIST1 gene have been found to cause a very rare disorder called Sweeney-Cox syndrome. Am 14: 1240-1247, 2006. They showed that each of the mutations studied (R248C, K650E, and G380R) constitutively activates the receptor, as evidenced by ligand-independent receptor tyrosine phosphorylation and cell proliferation. Kallmann syndrome (KS) is a genetic disorder that prevents a person from starting or fully completing puberty.Kallmann syndrome is a form of a group of conditions termed hypogonadotropic hypogonadism.To distinguish it from other forms of hypogonadotropic hypogonadism, Kallmann syndrome has the additional symptom of a total lack of sense of Genet.

Those with truncating mutations also tended to have a common facial phenotype, with midface hypoplasia, cleft lip/palate, and hypotelorism. Pfeiffer syndrome is a rare genetic disorder characterized by the premature fusion of certain bones of the skull (craniosynostosis) which affects the shape of the head and face. Impaired FGF signaling contributes to cleft lip and palate. Proc. The findings provided support for the hypothesis that the newly created cysteine residues may allow disulfide bonds to form between the extracellular domains of mutant monomers, thus inducing constitutive activation of the homodimer receptor complex.

Increased expression of Patched (601309) was observed, independent of unaltered expression of parathyroid hormone-related peptide receptor (168468) and Indian Hedgehog (Ihh; 600726), suggesting a new regulatory role for Fgfr3 in embryos.

The reduction in mineralized bone and lack of trabecular connectivity observed by microcomputed tomography were confirmed in histologic and histomorphometric analyses, which revealed a significant decrease in calcein labeling of mineralizing surfaces and a significant increase in osteoid in the long bones of 4-month-old Fgfr3 -/- mice.

(2006) concluded that a large proportion of epidermal nevi are caused by mosaicism of activating FGFR3 mutations in the human epidermis secondary to a postzygotic mutation in early embryonic development, and that the R248C mutation appears to be a hotspot for FGFR3 mutations in epidermal nevi. (1997) noted mental retardation in 4 of the 9 cases, which they reported was unrelated to the management of the craniosynostosis. The final adult height of individuals with Noonan syndrome is about 161167cm in males and 150155cm in females, which approaches the lower limit of normal.[8]. The mutation was not found in lymphocytic DNA from the parents; however, DNA analysis of a sperm sample from the 37-year-old father showed the G380R mutation. The phenotype is highly variable, and some patients may have midline facial defects and developmental delay. For short stature, growth hormone is sometimes combined with IGF-1 (or as an alternative, IGF-1 as a stand-alone) can be used to achieve an increased height/final height quicker.
