VPS13A

Chr 9

vacuolar protein sorting 13 homolog A

Also known as: BLTP5A, CHAC, CHOREIN

The protein controls steps in the cycling of proteins through the trans-Golgi network to endosomes, lysosomes and the plasma membrane, and localizes to the mitochondrial outer membrane. Mutations cause chorea-acanthocytosis, an autosomal recessive movement disorder characterized by progressive chorea and acanthocytes on blood smear.
