Precision Medicine in Heart Failure: How Genetic Testing Can Prevent Sudden Death

In this episode research geneticist and author Susan Liebman joins us to tell the personal and scientific story behind her memoir The Dressmaker’s Mirror: Sudden Death, Genetics, and a Jewish Family’s Secret.Susan unpacks generations of silence around heart disease and how sudden deaths and a decades-long family history of dilated cardiomyopathy led her to the discovery of an FLNC gene mutation (a "founder variant" most prevalent in Ashkenazi Jewish families) which revealed both risk and opportunity for preventing sudden cardiac death.Top 3 takeaways listeners will learn:Why dilated cardiomyopathy can be hereditary and how to get free genetic testing to find a treatable genetic variant.How precision medicine (including targeted screening, medications, implantable defibrillators, and soon gene editing) can change outcomes in cardiomyopathy — yet fewer than 1% of people with this condition currently receive germline genetic testing.Practical advice for starting conversations with family and clinicians, and how applying genetic knowledge can turn family grief into prevention for future generations.If you or a loved one has been diagnosed with heart failure or idiopathic dilated cardiomyopathy, this episode is a must-listen! It blends gripping storytelling with clear, actionable information about genetic testing, genes associated with heart failure and how knowing can help you gain access to precision medicine that could save lives for generations to come.META DESCRIPTIONSusan Liebman talks about cardiomyopathy, sudden death and family secrets. Her book is a love letter to family and shows how precision medicine found an FLNC gene mutation that can cause sudden death. Genetic testing can lead to treatments, preventative screenings, and lifesaving choices—yet fewer than 1% of cardiomyopathy patients get tested. We help you build the language and confidence to advocate for a precision medicine approach to your healthcare.
