VPS13A gene
URL of this page: https://medlineplus.gov/genetics/gene/vps13a/

VPS13A gene

vacuolar protein sorting 13 homolog A

Normal Function

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.

Health Conditions Related to Genetic Changes

Chorea-acanthocytosis

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.
