FGFR2, or Fibroblast Growth Factor Receptor 2, is a protein that plays a crucial role in cell growth, development, and tissue repair. It is part of a family of receptors that bind to fibroblast growth factors, which are important for various biological processes, including embryonic development and wound healing. Mutations in the FGFR2 gene can lead to various health conditions, including certain types of cancer and skeletal disorders. Understanding FGFR2 is essential for researchers and medical professionals as it can help in developing targeted therapies and improving treatment options for affected individuals.
