BACKGROUND Pantothenate kinase-associated neurodegeneration, PKAN, is an inherited disorder characterized by progressive impairment in motor coordination and caused by mutations in PANK2, a human gene that encodes one of four pantothenate kinase (PanK) isoforms. PanK initiates the synthesis of coenzyme A (CoA), an essential cofactor that plays a key role in energy metabolism and lipid synthesis...
Pantothenate kinase-associated neurodegeneration (PKAN) is a rare, inborn error of metabolism characterized by iron accumulation in the basal ganglia and by the presence of dystonia, dysarthria, and retinal degeneration. Mutations in pantothenate kinase 2 (PANK2), the rate-limiting enzyme in mitochondrial coenzyme A biosynthesis, represent the most common genetic cause of this disorder. How mut...
Hallervorden-Spatz disease (HSD) was and is known as a rare disorder primarily characterized by progressive extrapyramidal dysfunction and dementia alongside optic nerve atrophy or retinal degeneration and pyramidal signs. The rate of occurence of HSD is thus far unknown. Progress in DNA diagnostics stirred up a nomenclature and from HSD, or, perhaps better put, the Hallervorden-Spatz syndrome,...
BACKGROUND Pantothenate kinase associated neurodegeneration (PKAN) is the most prevalent type of neurodegeneration with brain iron accumulation (NBIA) disorders characterized by extrapyramidal signs, and 'eye-of-the-tiger' on T2 brain magnetic resonance imaging (MRI) characterized by hypointensity in globus pallidus and a hyperintensity in its core. All PKAN patients have homozygous or compound...
