Mutations in the corresponding genes cause different neurological diseases: Chorea-acanthocytosis, recently renamed as VPS13A disease (VPS13A) (Rampoldi et al, 2001; Ueno et al, 2001; Walker & Danek, 2021), Cohen syndrome (VPS13B) (Kolehmainen et al, 2003), Parkinson’s disease (VPS13C) (Lesage et al, 2016), and spastic ataxia (VPS13D) (Gauthier et al, 2018; Seong et al, 2018). This evidence concerns the gene VPS13A and chorea-acanthocytosis.
