What is the official name of the CSF1R gene?

The official name of this gene is “colony stimulating factor 1 receptor.”

CSF1R is the gene's official symbol. The CSF1R gene is also known by other names, listed below.

Read more about gene names and symbols on the About page.

What is the normal function of the CSF1R gene?

The CSF1R gene provides instructions for making a protein called the colony stimulating factor 1 receptor (CSF-1 receptor). This protein is found in the outer membrane of certain cell types. When a specific protein called colony stimulating factor 1 attaches (binds) to it, the receptor turns on (activates) a series of proteins inside the cell that are part of multiple signaling pathways. The signaling pathways stimulated by the CSF-1 receptor control many important cellular processes such as cell growth and division (proliferation) and maturation of cells to take on specific functions (differentiation).

In the brain, the CSF-1 receptor is abundant in the membrane of specialized cells called glial cells. These cells protect and maintain nerve cells (neurons). The CSF-1 receptor is thought to be involved in the proliferation and differentiation of glial cells, but its exact role in the brain is unclear.

Does the CSF1R gene share characteristics with other genes?

The CSF1R gene belongs to a family of genes called CD (CD molecules).

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 CSF1R gene related to health conditions?

adult-onset leukoencephalopathy with axonal spheroids and pigmented glia - caused by mutations in the CSF1R gene

More than a dozen mutations in the CSF1R gene have been found in people with adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP). ALSP is a severe neurological disorder characterized by damage to a type of brain tissue called white matter. Symptoms of this condition typically begin in adulthood and progress to severe cognitive and movement problems. Most CSF1R gene mutations in ALSP change single protein building blocks (amino acids) in the CSF-1 receptor. Other mutations change the sequence of amino acids in other ways. The mutations all occur in the region of the receptor that activates other proteins (called the kinase domain). It is likely that the altered receptor is unable to stimulate cell signaling pathways. However, it is unclear how the gene mutations lead to white matter damage or cognitive and movement problems in people with ALSP.

Where is the CSF1R gene located?

Cytogenetic Location: 5q32

Molecular Location on chromosome 5: base pairs 150,053,291 to 150,113,372

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBIThis link leads to a site outside Genetics Home Reference.)

The CSF1R gene is located on the long (q) arm of chromosome 5 at position 32.

The CSF1R gene is located on the long (q) arm of chromosome 5 at position 32.

More precisely, the CSF1R gene is located from base pair 150,053,291 to base pair 150,113,372 on chromosome 5.
