NBIA, according to the clinical phenotype associated with the genetic causes, is classified into pantothenate kinase-associated neurodegeneration (NBIA 1), PLA2G6-associated neurodegeneration (PLAN)/ infantile neuroaxonal dystrophy (INAD) (NBIA 2), neuroferritinopathy (NBIA 3), fatty acid hydroxylase-associated neurodegeneration (FAHN), mitochondrial membrane-associated neurodegeneration (MPAN), COASY protein-associated neurodegeneration (CoPAN), β-propeller-associated neurodegeneration (BPAN), Kufor-Rakeb syndrome and Woodhouse-Sakati syndrome [13, 14]. The gene discussed is FA2H; the disease is COASY protein-associated neurodegeneration.
