Pantothenate kinase‐associated neurodegeneration (PKAN, OMIM#234200, formerly known as Hallervorden‐Spatz syndrome), also called neurodegeneration with brain iron accumulation 1 (NBIA1), is the main form of NBIA.1 The two subtypes of PKAN include classic and atypical. This evidence concerns the gene PANK1 and pantothenate kinase-associated neurodegeneration.
