Long QT, Brugada Syndrome and CPVT Genetic Testing:

PGX Health offers the FAMILION® test to detect mutations that can cause cardiac channelopathies, including Long QT Syndrome (LQTS), Brugada Syndrome (BrS) and Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT). The FAMILION test is helpful in diagnosing these inherited heart rhythm disorders, guiding treatment plans and determining whether other family members are at risk.

Genetic Discrimination – A Call to Action  Genetics plays a large part in the lives of those of us with inherited heart rhythm disorders such as Long QT, Brugada Syndrome and Hypertrophic Cardiomyopathy. A genetic predisposition to a life-threatening event can affect health care, insurance and employment opportunities. The growing use of genetic information and its impact on our society will depend on the response of legal, political, and social institutions. C.A.R.E. Foundation suggests that affected families visit: http://www.geneticalliance.org to learn more about the Genetic Information Nondiscrimination Act (GINA) and to take action. If you or anyone you know has experienced genetic discrimination by insurance companies or employers, please contact C.A.R.E. at (800) 404-9500 or email us at care@CAREforhearts.org
