Combined Dendritic and Axonal Deterioration Are Responsible for Motoneuronopathy in Patient-Derived Neuronal Cell Models of Chorea-Acanthocytosis

  • Hannes Glaß,
  • Patrick Neumann,
  • Arun Pal,
  • Peter Reinhardt,
  • Alexander Storch,
  • Jared Sterneckert and
  • Andreas Hermann

Chorea acanthocytosis (ChAc), an ultra-rare devastating neurodegenerative disease, is caused by mutations in the VPS13A gene, which encodes for the protein chorein. Affected patients suffer from chorea, orofacial dyskinesia, epilepsy, parkinsonism as...
