FGFR2 (Fibroblast Growth Factor Receptor 2): FGFR2 is a receptor that binds fibroblast growth factors and plays a key role in cell growth, differentiation, and tissue repair. It is essential for normal development, and mutations in FGFR2 are linked to several developmental disorders such as craniosynostosis and skeletal dysplasia, as well as being implicated in certain cancers.
