The FAMILION tests detect mutations that can cause cardiac channelopathies, cardiomyopathies and other cardiopathies, rare, potentially lethal heart conditions, including Long QT Syndrome (LQTS), Brugada/J-Wave Syndromes (BrS/J-Wave), Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT), Familial Atrial Fibrillation (AF), Short QT Syndrome (SQTS), Hypertrophic Cardiomyopathy (HCM), Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC), Dilated Cardiomyopathy (DCM), Left Ventricular Noncompaction Cardiomyopathy (LVNC), and Marfan Syndrome and familial Thoracic Aortic Aneurysms and Dissections (TAAD). By reducing uncertainty and finding the specific causes of cardiac channelopathies, the test can:

• Help diagnose a patient's disease
• Guide treatment options
• Determine whether family members are at risk
