Among these, we designated two diseases as “core” NA syndromes, chorea-acanthocytosis (ChAc; autosomal recessive, OMIM #200150) and McLeod syndrome (X-linked recessive, OMIM #300842), grouping them with two additional disorders, Huntington’s disease-like 2 (HDL2; autosomal dominant, OMIM #606438) and pantothenate kinase-associated neurodegeneration (PKAN; autosomal recessive, OMIM #606157), in which acanthocytosis has also been reported. Here, PANK1 is linked to Huntington disease-like 2.
