What is the official name of the FOXC1 gene?
The official name of this gene is “forkhead box C1.”
FOXC1 is the gene's official symbol. The FOXC1 gene is also known by other names, listed below.

What is the normal function of the FOXC1 gene?
The FOXC1 gene provides instructions for making a protein that attaches (binds) to specific regions of DNA and regulates the activity of other genes. On the basis of this action, the FOXC1 protein is called a transcription factor.
The FOXC1 protein plays a critical role in early development, particularly in the formation of structures in the front part of the eye (the anterior segment). These structures include the colored part of the eye (the iris), the lens of the eye, and the clear front covering of the eye (the cornea). Studies suggest that the FOXC1 protein may also have functions in the adult eye, such as helping cells respond to oxidative stress. Oxidative stress occurs when unstable molecules called free radicals accumulate to levels that can damage or kill cells.
The FOXC1 protein is also involved in the normal development of other parts of the body, including the heart, kidneys, and brain.
Does the FOXC1 gene share characteristics with other genes?
The FOXC1 gene belongs to a family of genes called FOX (forkhead box genes).
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 FOXC1 gene related to health conditions?
Genetics Home Reference provides information about Dandy-Walker malformation, which is also associated with changes in the FOXC1 gene.
Where is the FOXC1 gene located?
Cytogenetic Location: 6p25
Molecular Location on chromosome 6: base pairs 1,610,446 to 1,613,897
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The FOXC1 gene is located on the short (p) arm of chromosome 6 at position 25.
More precisely, the FOXC1 gene is located from base pair 1,610,446 to base pair 1,613,897 on chromosome 6.
