What is the official name of the EGFR gene?
The official name of this gene is “epidermal growth factor receptor.”
EGFR is the gene's official symbol. The EGFR gene is also known by other names, listed below.

What is the normal function of the EGFR gene?
The EGFR gene provides instructions for making a receptor protein called the epidermal growth factor receptor, which spans the cell membrane so that one end of the protein remains inside the cell and the other end projects from the outer surface of the cell. This positioning allows the receptor to attach (bind) to other proteins, called ligands, outside the cell and to receive signals that help the cell respond to its environment. Ligands and receptors fit together like keys into locks. Epidermal growth factor receptor binds to at least seven different ligands. The binding of a ligand to an epidermal growth factor receptor allows the receptor to attach to a nearby receptor protein (dimerize), turning on (activating) the receptor complex. As a result, signaling pathways within the cell are triggered that promote cell growth and division (proliferation) and cell survival.
How are changes in the EGFR gene related to health conditions?
Where is the EGFR gene located?
