BACKGROUND Pantothenate-kinase-associated neurodegeneration (PKAN) is an autosomal recessive neurodegenerative disorder that is characterized by progressive extrapyramidal signs, visual loss, and cognitive impairment. PKAN is caused by mutations in the pantothenate kinase gene (PANK2), which is located on chromosome 20p13 and encodes pantothenate kinase, the key regulatory enzyme in coenzyme-A ...

BACKGROUND Congenital bilateral absence of the vas deferens (CBAVD) is a distinct clinical entity accounting for approximately 25% of obstructive azoospermia in infertile men. The association between CBAVD and mutated CFTR (cystic fibrosis transmembrane conductance regulator) alleles is well demonstrated in Caucasians, but the identity of CBAVD-susceptibility genes remains elusive in Asians. We...

Abstract Pantothenate kinase-associated neurodegeneration (PKAN) is a rare hereditary neurodegenerative disease characterized by an accumulation of iron within the brain. In present report, we describe family with 4 affected siblings presenting variable clinical manifestations, e.g., parkinsonian features, dystonia and slow progression over 5 years. Exome sequencing revealed causative ...

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...

Pantothenate kinase-associated neurodegeneration (PKAN) is a neurodegenerative disease belonging to the group of neurodegeneration with brain iron accumulation disorders. It is characterized by progressive impairments in movement, speech and cognition. The disease is inherited in a recessive manner due to mutations in the Pantothenate Kinase-2 (PANK2) gene that encodes a mitochondrial protein i...

AIMS Mutations in the pantothenate kinase 2 gene (PANK2) are responsible for the most common type of neurodegeneration with brain iron accumulation (NBIA), known as pantothenate kinase-associated neurodegeneration (PKAN). Historically, NBIA is considered a synucleinopathy with numerous reports of NBIA cases with Lewy bodies and Lewy neurites and some cases reporting additional abnormal tau accu...

Pantothenate kinase-associated neurodegeneration (PKAN), a rare neurological disorder occurs by variation(s) in the PANK2 (Pantothenate kinase 2) gene and is linked to iron accumulation basal ganglia. The researchers have carried out targeted sequencing of all exons patient with suspected phenotype PKAN. A missense variant exon 6 (NM_153638.3:c.1583C>T,NP_705902.2:p.Thr528Met) has been ident...

Neurodegeneration with brain iron accumulation (NBIA) describes a group of progressive extrapyramidal disorders with radiographic evidence of focal iron accumulation in the brain, usually in the basal ganglia. Patients previously diagnosed with Hallervorden-Spatz syndrome fall into this category. Mutations in the PANK2 gene account for the majority of NBIA cases and cause an autosomal recessive...
