Transcriptional profiling of ion channel genes in Brugada syndrome and other right ventricular arrhythmogenic diseases.

Abstract excerpt

AIMS: Brugada syndrome is an inherited sudden-death arrhythmia syndrome. Na(+)-current dysfunction is central, but mutations in the SCN5A gene (encoding the cardiac Na(+)-channel Nav1.5) are present in only 20% of probands. This study addressed the possibility that Brugada patients display specific expression patterns for ion-channels regulating cardiac conduction, excitability, and repolarization. METHODS AND...
