Novel Cardiocerebral Channelopathy Associated with a <i>KCND3</i> V392I Mutation

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...

Clinical Diversity of SCN4A-Mutation-Associated Skeletal Muscle Sodium Channelopathy

BACKGROUND AND PURPOSE Mutations of the skeletal muscle sodium channel gene SCN4A, which is located on chromosome 17q23-25, are associated with various neuromuscular disorders that are labeled collectively as skeletal muscle sodium channelopathy. These disorders include hyperkalemic periodic paralysis (HYPP), hypokalemic periodic paralysis, paramyotonia congenita (PMC), potassium-aggravated myo...

Pheochromocytomatosis associated with a novel TMEM127 mutation

Pheochromocytomatosis, a very rare form of pheochromocytoma recurrence, refers to new, multiple, and often small pheochromocytomas growing in and around the surgical resection bed of a previous adrenalectomy for a solitary pheochromocytoma. We here report a case of pheochromocytomatosis in a 70-year-old female. At age 64 years, she was diagnosed with a 6-cm right pheochromocytoma. She underwent...

A Novel Splice Site Mutation in HPS1 Gene is Associated with Hermansky-Pudlak Syndrome-1 (HPS1) in an Iranian Family

a novel missense mutation, e1623g, in the human factor viii gene associated with moderate haemophilia a

introduction: haemophilia a is the most common inherited x-linked recessive bleeding disorder. the severity of the resultant bleeding diathesis depends on the fviii levels associated with the mutation. analysis of carrier state can be made indirectly by dna linkage analysis or directly by identifying the mutation that leads to the disease. the aim of this study was to identification of the caus...
