Identifying at-risk patients and family members is often lifesaving. An estimated 1:70 individuals in the general population are estimated to carry monogenic cardiovascular disease.
Are some heart diseases more likely to be inherited?
| Example of Heart Disease | Estimated percentage of disease due to inherited genetic mutation |
|---|---|
| Hypertrophic cardiomyopathy | 40-60% |
| Dilated cardiomyopathy | 20-50% |
| Arrhythmogenic cardiomyopathy | 50-65% |
| Long QT Syndrome | 75-85% |
| Brugada Syndrome | 20% |
| Aortic aneurysm and dissection | 30% |
| Familial Hypercholesterolemia | 60-80% |
Did You Know?
| Positive result: Diagnostic of hereditary heart disease/condition. Consider family follow up genetic testing. | |
| Negative Result: No genetic mutation identified, often does not rule out clinical condition. Patients may still be at risk due to personal or family history. | |
| Variant of unknown significance: At least one genetic variant was found, but it is unclear if this change causes the cardiovascular disorder or not. Variant classification may change as more information is learned over time. |
