Genetic Testing

Genetic testing allows us to look at your DNA to identify any differences that could predispose you to developing certain health problems.

In some cases genetic testing may be used to diagnose an inherited cardiac disease.  However, in most cases genetic testing is used to help determine which family members could develop the heart problems that are running in the family and which family members will not develop those heart problems.  Genetic testing is first done on a family member who has the inherited heart condition.  The aim of this test is to identify the difference in the DNA (called a mutation) that is the cause of the individual’s heart condition.   Once the mutation has been found, other family members can have genetic testing to find out whether or not they inherited the mutation and could develop the heart condition that’s running in the family.

We recommend genetic counseling before genetic tests are ordered to discuss the implications of the testing for you and your family. When results are available our team will make recommendations about follow up for both you and your family, based on the results.
