A novel mutation in KCNA1 causes episodic ataxia without myokymia.
We describe a unique family in which several individual are affected with episodes of ataxia that best fit the phenotype of episodic ataxia type 2 (EA2). All of the affected family members had episodes typically lasting for several hours, and none of them had muscle abnormalities including myokymia. Episodic ataxia type 1 (EA1) was not considered initially as a clinical diagnosis for the affect...
متن کاملA novel KCNA1 mutation causing episodic ataxia type I.
We describe the clinical phenotype of a novel de novo KNCA1 mutation, and functional characterization of the effects of the mutation on Kv1.1 channel function. HEK293 cells were transfected transiently with either wild-type or mutant channels. Representative currents were evoked after application of a series of square voltage steps from -80 mV to +50 mV in 200-ms intervals from Vh = -80 mV. Ext...
متن کاملEpisodic ataxia associated with EAAT1 mutation C186S affecting glutamate reuptake.
BACKGROUND Episodic ataxia (EA) is variably associated with additional neurologic symptoms. At least 4 genes have been implicated. Recently, a mutation in the SLC1A3 gene encoding the glutamate transporter EAAT1 was identified in a patient with severe episodic and progressive ataxia, seizures, alternating hemiplegia, and migraine headache. The mutant EAAT1 showed severely reduced uptake of glut...
متن کاملHereditary Ataxia with a Novel Mutation in the Senataxin Gene: A Case Report
Hereditary ataxias (HA) are a group of inherited neurological disorders caused by changes in genes. At least 115 different mutations in the senataxin (SETX) gene causing ataxia have been identified. There are no reports of any SETX gene mutation among the Iranian population. Here we report on two cases with homozygous and heterozygous mutations in which one patient was affected by HA with oculo...
متن کاملAcetazolamide-responsive exercise-induced episodic ataxia associated with a novel homozygous DARS2 mutation.
BACKGROUND Leukoencephalopathy with brain stem and spinal cord involvement and brain lactate elevation (LBSL) was recently shown to be caused by mutations in the DARS2 gene, encoding a mitochondrial aspartyl-tRNA synthetase. So far, affected individuals were invariably compound heterozygous for two mutations in DARS2, and drug treatments have remained elusive. METHODS Prospective 2-year follo...
