Neurodegeneration with brain iron accumulation (NBIA) is a group of progressive extrapyramidal and cognitive disorders characterized by iron accumulation predominantly in the globus pallidus, as well as extensive axonal spheroids in various regions of the brain. The most frequent genetic form is the pantothenate kinase-2 associated neurodegeneration (PKAN) with a mutation in the pantothenate kinase 2 (PANK2) gene. Other forms are associated with a mutation in phospholipase A2 (PLA2G6), and FTL (neuroferritinopathy). A significant proportion of children with an NBIA phenotype have no genetic diagnosis and there are additional as yet undiscovered genes that account for a number of these cases.
