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.

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 defined functions (differentiation).

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?

hereditary diffuse leukoencephalopathy with spheroids - caused by mutations in the CSF1R gene

More than a dozen mutations in the CSF1R gene have been found in people with hereditary diffuse leukoencephalopathy with spheroids (HDLS). HDLS 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 HDLS 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. It is unclear, though, how the gene mutations lead to white matter damage or cognitive and movement problems in people with HDLS.

Where is the CSF1R gene located?

Cytogenetic Location: 5q32

Molecular Location on chromosome 5: base pairs 150,053,290 to 150,113,371

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 150,053,290 to base pair 150,113,371 on chromosome 5.
