    Summary
    This gene encodes a subunit of a voltage-dependent calcium channel protein that is a member of the voltage-gated calcium channel superfamily. The gene product was originally identified as an antigen target in Lambert-Eaton myasthenic syndrome, an autoimmune disorder. Mutations in this gene are associated with Brugada syndrome. Alternatively spliced variants encoding different isoforms have been described. [provided by RefSeq, Feb 2013]

    Brugada syndrome 4

    Summary from GeneReviews: Brugada Syndrome Go to GeneReviews

    Disease Characteristics
    Brugada syndrome is characterized by cardiac conduction abnormalities (ST-segment abnormalities in leads V1-V3 on ECG and a high risk for ventricular arrhythmias) that can result in sudden death. Brugada syndrome presents primarily during adulthood; however, age at diagnosis ranges from two days to 85 years. The mean age of sudden death is approximately 40 years. Clinical presentations may also include sudden infant death syndrome (SIDS) (death of a child during the first year of life without an identifiable cause) and the sudden unexpected nocturnal death syndrome (SUNDS), a typical presentation in individuals from Southeast Asia. Other conduction defects can include first-degree AV block, intraventricular conduction delay, right bundle branch block, and sick sinus syndrome.
    Diagnosis Testing
    Diagnosis is based on clinical findings. Mutations in eight genes (SCN5A, GPD1L, CACNA1C, CACNB2, SCN1B, KCNE3, SCN3B, and HCN4) are known to cause Brugada syndrome. Molecular genetic testing for all eight genes is available clinically.
    Genetic Counseling
    Brugada syndrome is inherited in an autosomal dominant manner. Most individuals diagnosed with Brugada syndrome have an affected parent. The proportion of cases caused by a de novo mutation is estimated at 1%. Each child of an individual with Brugada syndrome has a 50% chance of inheriting the mutation. Prenatal testing for pregnancies at increased risk is possible if the disease-causing mutation in the family is known.
