About Fgfr3

Chromosome 5: 33,879,018-33,894,412 forward strand.GRCm39:CM000998.3

This gene has 17 transcripts (splice variants), 191 orthologues, 53 paralogues and is associated with 200 phenotypes. Broad expression in lung adult (RPKM 46.), limb E14.5 (RPKM 23.9) and 21 other tissues.

Summary

This gene encodes a member of the Fibroblast Growth Factor receptor family. Members of this family are highly conserved proteins that differ from one another in their ligand affinities and tissue distribution. A representative protein consists of an extracellular region composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment, and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This family member binds acidic and basic fibroblast growth hormone and plays a role in bone development and maintenance. Mutations in this gene may be associated with craniosynostosis and multiple types of skeletal dysplasia. A pseudogene of this gene is located on chromosome 1. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Apr 2011]
