Cardiac Genetics Program
Seattle Children's Cardiac Genetics Program
By far, most heart defects in children have no known genetic cause. But in this rapidly changing field, doctors are getting more and more clues about the role of genetics in the development of the heart.
What services do you offer?
This program involves consultation, evaluation and counseling before and after your child is born. You will talk with doctors and genetic counselors about your family risk of having a child with a heart defect. By knowing more about the risks, your family can evaluate the options better.
In many cases, assessing your risk is all that's needed. For instance, the risk of having a baby with a heart defect is 1%, or 1 in 100 children. If you or your child has a heart defect, the risk of another child being born with a heart defect increases. Certain heart defects have a much higher risk of being passed on, particularly:
You may make an appointment with the Cardiac Genetics Clinic at Children's on your own or seek a referral from your primary care doctor.
Depending on the risk factors, an echocardiogram may be done on one or more family members. Blood tests may be performed to look at genetic markers in the chromosomes. Often, we will involve other heart specialists or consultants.
