A Novel Nonsense mutation in PANK2 Gene in Two Patients with Pantothenate Kinase-Associated Neurodegeneration
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...

متن کاملEye-of-the-Tiger sign is not Pathognomonic of Pantothenate Kinase-Associated Neurodegeneration in Adult Cases
An eye-of-the-tiger sign is previously known to have one-to-one correlation with pantothenate kinase-associated neurodegeneration (PKAN). Reviewing the literature on this subject, the correlation between eye-of-the-tiger sign and PKAN seems to show an interesting hypothesis that differs from conventional conclusion. We analyze the published papers in an attempt to reflect this trend and illustr...
متن کاملpantothenate kinase 2 mutation with eye-of-the-tiger sign on magnetic resonance imaging in three siblings.
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 compoun...
