Genetic Testing for Hypertrophic Cardiomyopathy (HCM)

Take Charge of Your Health If You’re at Risk for Inherited HCM

Hypertrophic cardiomyopathy (HCM) often runs in families. Males and females are equally affected. Gene mutations in the part of the heart responsible for contracting (sarcomere) are responsible for the condition.

Sometimes, however, only one family member has the disease. This suggests there may also be other non-genetic causes of HCM. Family screening and genetic tests can help identify those who have the condition or are at risk for it.

Family Screening for HCM

At Lahey Clinic, we recommend HCM screening for family members of those with a known HCM diagnosis. Screening may find HCM before symptoms appear. Tests include MRI scans and echocardiography.

Genetic Testing for HCM

Our HCM cardiologists provide comprehensive genetic counseling for HCM to families who may be at risk. We discuss the benefits of testing as well as the potential financial, psychological and insurance limitations. We also answer any questions you might have.

Genetic testing may identify those who carry the gene mutation that could lead to HCM in the future. Testing involves collecting blood samples or swabbing the inside of your cheeks. We send these samples to a laboratory and get the results in four to six weeks.

Expert, Team-Based Care

If screening or genetic tests are positive, we have a team of HCM specialists ready to help. Working together, they manage your care in an effort to help you take control of your condition.

Keep in mind, genetic testing doesn’t tell us if your HCM will run the same course as another family member. It also doesn’t determine if we will manage your disease in the same way. We test solely to identify those who may be at risk for developing HCM. We individualize care to help you have the best possible outcome.
