<unk>  is a label applied to several genetic neurological conditions in which the blood contains misshapen, spiculated red blood cells called acanthocytes. The 'core'<unk>  syndromes, in which acanthocytes are a typical feature, are chorea acanthocytosis and McLeod syndrome. Acanthocytes are seen less frequently in other conditions including Huntington's disease-like syndrome 2 (HDL2) and pantothenate kinase-associated neurodegeneration (PKAN). The<unk>  syndromes are caused by a range of genetic mutations and produce a variety of clinical features but primarily produce neurodegeneration of the brain, specifically the basal ganglia. The diseases are hereditary but rare.
