Mutation Load of Multiple Ion Channel Gene Mutations in Brugada Syndrome

Abstract excerpt

Brugada syndrome is a primary arrhythmic syndrome that accounts for 20% of all sudden cardiac death cases in individuals with a structurally normal heart. Pathogenic variants associated with Brugada syndrome have been identified in over 19 genes, with SCN5A as a pivotal gene accounting for nearly 30% of cases. In contrast to other arrhythmogenic channelopathies (such as long QT syndrome), digenic inheritance has...
