In the near future you will find more info on the various types of VPS13:

- VPS13A, ORPHA:2388
Also known as Chorea-acanthocytosis, a form of neuroacanthocytosis and is characterized clinically by a Huntington disease-like phenotype with progressive neurological symptoms including movement disorders, psychiatric manifestations and cognitive disturbances.

- VPS13B, ORPHA:193
Also known as Cohen Syndrome, is a rare developmental defect during embryogenesis characterized by microcephaly, characteristic facial features, hypotonia, non-progressive intellectual deficit, myopia and retinal dystrophy, neutropenia and truncal obesity.

- VPS13C, ORPHA:2828
Also known as Early-onset Parkinson disease, YOPD, or early-onset Parkinson's disease and spastic ataxia.

- VPS13D, ORPHA:95434
Also known as SCAR4, is a rare hereditary ataxia characterized by a progressive cerebellar ataxia, pyramidal signs, neuropathy, and macrosaccadic intrusions, generally developing in early adulthood. SCAR4 has been reported to be caused by many gene mutations, and mutations in the vacuolar protein sorting–associated protein 13D isoform 1 (hence the name VPS13D) gene.
