Neuroacanthocytosis (NA) is a group of rare hereditary diseases with the common clinical features of neurological degeneration and peripheral acanthocytosis, initially thought to include VPS13A disease (chorea-acanthocytosis, ChAc), XK disease (McLeod syndrome, MLS), Huntington’s disease-like 2 (HDL2), and pantothenate kinase-associated neurodegeneration (PKAN) (1). The gene discussed is VPS13A; the disease is chorea-acanthocytosis.
