The Brugada syndrome (BRS) is an autosomal dominant genetic disorder that is characterised by abnormal electrocardiogram (ECG) findings and an increased risk of sudden cardiac death. Diagnosis is based on clinical findings. Mutations in nine genes (SCN5A, GPD1L, CACNA1C, CACNB2, SCN1B, KCNE3, SCN3B, HCN4, and KCND3) are known to cause BRS. In approximately 20% of the cases BRS is caused by mutations in the SCN5A gene, encoding the cardiac sodium channel.
