Discover even more about cardiovascular diseases

More tests. More data. More answers for your patients.
GeneDx offers an unmatched breadth of tests and depth of patient data in the cardiology field, enabling more accurate variant interpretation and less uncertainty for your patients.


Experts in moving cardiovascular genetic testing forward

Variant classification is a complex, continually evolving process. Backed by over 20 years of experience and a database housing over one million tests, we’re experts at helping you understand current guidelines for clinical evaluation and indications for testing, the difference between a pathogenic result and a variant of uncertain significance (VUS), and the implications each has related to recommendations for family members.

Support, every step of the way

Determining whether patients with cardiac indications will benefit from genetic testing is not always easy. A family history of certain types of heart disease, heart attacks, coronary artery disease, or cholesterol disease, are not immediate indicators. We can help you take a diagnosis-focused approach to genetic testing, no matter the condition, indication, or symptom.


Where we can help you diagnose

  • Early disease onset/childhood-onset disease, multiple affected family members, multiple generations affected
  • Inherited cardiomyopathy (Hypertrophic, dilated, arrhythmogenic, left ventricular non-compaction)
  • Arrhythmia (Long QT Syndrome, Short QT Syndrome, Brugada Syndrome, Catecholaminergic polymorphic ventricular tachycardia)
  • Cardiac arrest
  • Sudden death
  • Marfan Syndrome
  • Familial thoracic aortic aneurysm and dissection
  • Connective tissue disease
  • Familial hypercholesterolemia/dyslipidemia

Providing clarity when you need it most

Whether you have a patient presenting with a specific phenotype like Long QT Syndrome, or if the clinical picture is less clear, our extensive testing menu provides a range of options for every indication.

We offer preselected cardiology reflex tests to enable a seamless testing approach that reduces testing costs. When healthcare providers order a targeted cardiology panel at the same time as the preselected reflex test, we test the targeted panel first to decrease the likelihood of detecting a VUS in a gene unrelated to the patient's clinical phenotype. Then, if we do not identify a disease-causing variant with the targeted panel, we begin the more comprehensive reflex test at no additional cost.

Partners in life’s most challenging moments

For situations involving familial disease, at times, the best person to test is the deceased. We work with cardiologists, medical examiners, coroners, and genetic counselors to coordinate post-mortem testing and work with the medical examiners or coroners to determine a testing solution based on what specimen types are available.
