ONLINE MUTATION REPORT Unconventional intronic splice site mutation in SCN5A associates with cardiac sodium channelopathy
Background: Mutations in the cardiac sodium channel, SCN5A, have been associated with one type of long-QT syndrome, with isolated cardiac conduction defects and Brugada syndrome. The sodium channelopathies exhibit marked variation in clinical phenotypes. The mechanisms underlying the phenotypical diversity, however, remain unknown. Exonic SCN5A mutations can be detected in 20% of Brugada syndro...

متن کاملA novel intronic splice site tafazzin gene mutation detected prenatally in a family with Barth syndrome
Barth syndrome (BTHS) is a rare X-linked disease characterized by dilated cardiomyopathy, proximal skeletal myopathy and cyclic neutropenia. It is caused by various mutations in the tafazzin (TAZ) gene located on Xq28 that results in remodeling of cardiolipin and abnormalities in mitochondria stability and energy production. Here we report on a novel c.285-1G>C splice site mutation in intron 3 ...
متن کاملFactor VII gene intronic mutation in a lethal factor VII deficiency: effects on splice-site selection.
In a patient with lethal factor VII (FVII) deficiency, 2 homozygous nucleotide substitutions were identified in the F7 gene: a IVS7+2T>G transversion involving the IVS7 donor splice site, followed by a mutation at nucleotide 10588 that would result in a missense variation (Arg224Gln). The mutated splice site, located within the first repeat of a minisatellite, is followed by a variable number o...
متن کاملVariable phenotype expression with a frameshift mutation of the cardiac sodium channel gene SCN5A
Loss-of-function mutations in the cardiac sodium channel α-subunit gene SCN5A result in multiple inherited arrhythmic syndromes. This case report describes 2 unrelated probands carrying an identical SCN5A frameshift mutation, V1764fsX1786, who exhibited distinct clinical manifestations: progressive cardiac conduction defect (PCCD)/Brugada syndrome (patient #1) and idiopathic ventricular fibrill...
