چکیده
Neurodegeneration with brain iron accumulation is a group of disorders, the commonest of which is PKAN (Pantothenate kinase associated neurodegeneration). We present here, a case of 18 year old boy with progressive dementia, pyramidal and extrapyramidal involvement, dysarthria, seizures and myoclonus. The patient was diagnosed as PKAN (formerly Hallervorden Spatz disease) after "eye of tiger" appearance on neuro-imaging.

Pantothenate kinase- associated neurodegeneration (PKAN) syndrome is a rare autosomal recessive disorder characterized by progressive extrapyramidal dysfunction and iron accumulation in the brain and axonal spheroids in the central nervous system. It has been shown that the disorder is caused by mutations in PANK2 gene which codes for a mitochondrial enzyme participating in coenzyme A biosynthe...

Pantothenate kinase-associated neurodegeneration (formerly Hallervorden-Spatz syndrome), the most prevalent form of neurodegeneration with brain iron accumulation, is a rare degenerative brain disease characterised by predominantly extrapyramidal dysfunction resulting from mutations in the PANK2 (pantothenate kinase 2) gene. Using DNA mutation analysis, the authors identified a novel missense m...

Pantothenate kinase-associated neurodegeneration, caused by mutations in the PANK2 gene, is an autosomal recessive disorder characterized by dystonia, dysarthria, rigidity, pigmentary retinal degeneration and brain iron accumulation. PANK2 encodes the mitochondrial enzyme pantothenate kinase type 2, responsible for the phosphorylation of pantothenate or vitamin B5 in the biosynthesis of co-enzy...

Pantothenate kinase-associated neurodegeneration is a form of neurodegeneration with brain iron accumulation, characterized by a progressive movement disorder and prominent iron deposition in the globus pallidus. Formerly referred to as Hallervorden-Spatz syndrome, the disorder was renamed pantothenate kinase-associated neurodegeneration after discovery of the causative gene, PANK2. Although th...
متن کاملNovel PANK2 mutation in the first Greek compound heterozygote patient with pantothenate-kinase-associated neurodegeneration
Pantothenate-kinase-associated neurodegeneration is the most common autosomal recessive form of neurodegeneration with brain iron accumulation. Less than 100 mutations in PANK2 gene (20p13) are responsible for classic and atypical cases. We report here the first Greek case of atypical pantothenate-kinase-associated neurodegeneration, confirmed by molecular analysis that revealed two trans-actin...
