Preferred Label : Brugada syndrome 1;

Symbol : BRGDA1;

CISMeF acronym : BRGDA1;

Description : Brugada syndrome is characterized by an ST-segment elevation in the right precordial electrocardiogram leads (so-called type 1 ECG) and a high incidence of sudden death in patients with structurally normal hearts. The syndrome typically manifests during adulthood, with a mean age of sudden death of 41 /- 15 years, but occurs in infants and children (summary by Antzelevitch et al., 2005). - Genetic Heterogeneity of Brugada Syndrome Brugada syndrome-2 (611777) is caused by mutation in the GPD1L gene (611778). Brugada syndrome-3 (611875) and Brugada syndrome-4 (611876), the phenotypes of which include a shortened QT interval on ECG, are caused by mutation in the CACNA1C (114205) and CACNB2 (600003) genes, respectively. Brugada syndrome-5 (612838) is caused by mutation in the SCN1B gene (600235). Brugada syndrome-6 (613119) is caused by mutation in the KCNE3 gene (604433). Brugada syndrome-7 (613120) is caused by mutation in the SCN3B gene (608214). Brugada syndrome-8 (613123) is caused by mutation in the HCN4 gene (605206).;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the sodium channel, voltage-gated, type V, alpha subunit gene (SCN5A, 600163.0004);

Prefixed ID : #601144;
