What is the official name of the VPS13A gene?

The official name of this gene is “vacuolar protein sorting 13 homolog A (S. cerevisiae).”

VPS13A is the gene's official symbol. The VPS13A gene is also known by other names, listed below.

What is the normal function of the VPS13A gene?

The VPS13A gene provides instructions for producing a protein called chorein. Chorein is found in various tissues throughout the body. The function of this protein is unknown. Some researchers believe that chorein plays a role in the movement of proteins within cells.

How are changes in the VPS13A gene related to health conditions?

chorea-acanthocytosis - caused by mutations in the VPS13A gene

Approximately 75 mutations in the VPS13A gene have been found to cause chorea-acanthocytosis. Most of these mutations insert or delete one or more building blocks of DNA (nucleotides) in the VPS13A gene. These changes in the gene lead to the production of an abnormally small, nonfunctional version of chorein. Many of the mutations are specific to single families, although people with chorea-acanthocytosis who are French-Canadian or Japanese tend to have a mutation that is specific to their population. It is unclear why mutations in the VPS13A gene affect only the brain and red blood cells, causing the signs and symptoms of chorea-acanthocytosis.

Where is the VPS13A gene located?

Cytogenetic Location: 9q21

Molecular Location on chromosome 9: base pairs 77,177,353 to 77,417,483

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

The VPS13A gene is located on the long (q) arm of chromosome 9 at position 21.

The VPS13A gene is located on the long (q) arm of chromosome 9 at position 21.

More precisely, the VPS13A gene is located from base pair 77,177,353 to base pair 77,417,483 on chromosome 9.
