Brugada Syndrome

Overview

Type of disease: Rare conditions

Brugada syndrome is a condition that causes a disruption of the heart’s normal rhythm (arrhythmia). Signs and symptoms usually develop in adulthood and include ventricular arrhythmia that can cause fainting, seizures, difficulty breathing, or sudden death. These complications often occur when an affected person is resting or asleep. Brugada syndrome is inherited in an autosomal dominant manner and may be caused by a mutation in any of several genes (most commonly the SCN5A gene). In many cases, the genetic cause is not identified. There have also been reports of acquired Brugada syndrome which have been associated with adverse reactions to certain drugs or other substances. Treatment may include use of an implantable cardioverter defibrillator (ICD) in people with a history of fainting or heart attack.Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
