TL;DR: Overall, 21% of BrS probands have mutations in SCN5A compared to the 2% to 5% background rate of rare variants reported in healthy control subjects, which may help further distinguish pathogenic mutations from similarly rare but otherwise innocuous ones found in cases.
Journal ArticleDOI
Sodium channel β1 subunit mutations associated with Brugada syndrome and cardiac conduction disease in humans

TL;DR: Findings implicate SCN1B as a disease gene for human arrhythmia susceptibility, which encodes the function-modifying sodium channel beta1 subunit, in 282 probands with Brugada syndrome and in 44 patients with conduction disease, none of whom had SCN5A mutations.
Journal ArticleDOI
Right Ventricular Fibrosis and Conduction Delay in a Patient With Clinical Signs of Brugada Syndrome A Combined Electrophysiological, Genetic, Histopathologic, and Computational Study
Ruben Coronel,Simona Casini,Tamara T. Koopmann,Francien J.G. Wilms-Schopman,Arie O. Verkerk,Joris R. de Groot,Zahurul A. Bhuiyan,Connie R. Bezzina,Marieke W. Veldkamp,André C. Linnenbank,Allard C. van der Wal,Hanno L. Tan,Pedro Brugada,Arthur A.M. Wilde,Jacques M.T. de Bakker +14 more
TL;DR: In this patient with BS, conduction slowing based on interstitial fibrosis, but not transmural repolarization differences, caused the ECG signs and was the origin of ventricular fibrillation.
Journal ArticleDOI

TL;DR: In this paper, the authors identified 35 common variant loci associated with QT interval that collectively explain ∼8-10% of QT-interval variation and highlight the importance of calcium regulation in myocardial repolarization.
Journal ArticleDOI

TL;DR: The results provide support for the hypothesis that mutations in SCN3B can lead to loss of transport and functional expression of the hNav1.5 protein, leading to reduction in sodium channel current and clinical manifestation of a Brugada phenotype.
