Chorea‐acanthocytosis (ChAc), occasionally still known as “Levine–Critchley syndrome,” is one of four core neuroacanthocytosis (NA) syndromes, next to McLeod syndrome, Huntington's disease‐like 2 (HDL2), and pantothenate kinase‐associated neurodegeneration (PKAN) (Danek, 2004; Peikert, Danek, & Hermann, 2018; Velayos Baeza et al., 2002; Walker, 2015; Walker, Saiki, & Danek, 2008). This evidence concerns the gene PANK1 and Choreoacanthocytosis.
