What is the official name of the FGFR4 gene?
The official name of this gene is “fibroblast growth factor receptor 4.”
FGFR4 is the gene's official symbol. The FGFR4 gene is also known by other names, listed below.

What is the normal function of the FGFR4 gene?
The FGFR4 gene provides instructions for making a protein called fibroblast growth factor receptor 4. This protein is part of a family of fibroblast growth factor receptors that share similar structures and functions. These receptor proteins play a role in important processes such as cell division, regulating cell growth and maturation, formation of blood vessels, wound healing, and embryo development.
The FGFR4 protein interacts with specific growth factors to conduct signals from the environment outside the cell to the nucleus. The nucleus responds to these signals by switching on or off appropriate genes that help the cell adjust to changes in the environment. In response, the cell might divide, move, or mature to take on specialized functions. Although specific functions of FGFR4 remain unclear, studies indicate that the gene is involved in muscle development and the maturation of bone cells in the skull. The FGFR4 gene may also play a role in the development and maintenance of specialized cells (called foveal cones) in the light-sensitive layer (the retina) at the back of the eye.
Does the FGFR4 gene share characteristics with other genes?
The FGFR4 gene belongs to a family of genes called CD (CD molecules). It also belongs to a family of genes called immunoglobulin superfamily, I-set domain containing (immunoglobulin superfamily, I-set domain containing).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
How are changes in the FGFR4 gene related to health conditions?
Genetics Home Reference provides information about prostate cancer, which is also associated with changes in the FGFR4 gene.
Where is the FGFR4 gene located?
Cytogenetic Location: 5q35.2
Molecular Location on chromosome 5: base pairs 177,086,871 to 177,098,141
The FGFR4 gene is located on the long (q) arm of chromosome 5 at position 35.2.
More precisely, the FGFR4 gene is located from base pair 177,086,871 to base pair 177,098,141 on chromosome 5.
