What is the official name of the CLIP2 gene?

The official name of this gene is “CAP-Gly domain containing linker protein 2.”

CLIP2 is the gene's official symbol. The CLIP2 gene is also known by other names, listed below.

What is the normal function of the CLIP2 gene?

The CLIP2 gene provides instructions for making a protein called CAP-Gly domain containing linker protein 2. The protein is also known as CLIP-115. This protein is found predominantly in the brain, where it likely plays a role in the normal structure and function of nerve cells. Within cells, this protein is thought to regulate aspects of the cytoskeleton, the structural framework that helps to determine cell shape, size, and movement. The protein is associated with microtubules, which are rigid, hollow fibers that make up a significant part of the cytoskeleton. Microtubules help cells maintain their shape, assist in the process of cell division, and are essential for the transport of materials within cells.

How are changes in the CLIP2 gene related to health conditions?

Williams syndrome - associated with the CLIP2 gene

The CLIP2 gene is located in a region of chromosome 7 that is deleted in people with Williams syndrome. As a result of this deletion, people with this condition are missing one copy of the CLIP2 gene in each cell. Studies suggest that the loss of this gene may contribute to some of the characteristic features of Williams syndrome, including the unique behavioral traits and other symptoms involving the nervous system. A deletion of this gene probably disrupts the normal regulation of the cytoskeleton and affects the structure of nerve cells in the brain. It is not known how these changes may be related to the characteristic signs and symptoms of Williams syndrome.

Where is the CLIP2 gene located?

Cytogenetic Location: 7q11.23

Molecular Location on chromosome 7: base pairs 74,289,475 to 74,405,943

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBI (

The CLIP2 gene is located on the long (q) arm of chromosome 7 at position 11.23.

The CLIP2 gene is located on the long (q) arm of chromosome 7 at position 11.23.

More precisely, the CLIP2 gene is located from base pair 74,289,475 to base pair 74,405,943 on chromosome 7.
