Test Code
C6012
Test Name
Brugada Syndrome NGS Panel
CPT Codes
81407
Expected Turnaround Time
Typically 2 to 4 weeks from receipt of a sample in the laboratory. All cases involving ongoing pregnancies will be expedited.
Clinical Utility
Genetic analysis to provide a molecular diagnosis of Brugada syndrome. Brugada syndrome is a cardiac channelopathy characterized by specific ECG abnormalities such as ST-segment elevation in the right precordial leads and incomplete right bundle-branch block. Typical findings include ventricular fibrillation, syncope and cardiac arrest. Brugada syndrome is associated with high risk of sudden cardiac death in otherwise healthy young adults. The age-of-onset is usually in the adulthood, however, sudden infant death syndrome is one of the clinical presentations. Recommended for individuals with a personal and/or family history of Brugada syndrome to ensure appropriate treatment and establish recurrence risk for family members.
