Is congenital heart disease genetic?

5 doctors agree
In brief: Some of it
Even though 8 out of every 1000 babies born will have have some form of heart defect, when there is a first line family member affected the number goes up to about 16-30/1000 (for some particular defects this number will be higher) so this would suggest a genetic component.
..We just haven't learned enough about genetics and the heart to be more precise, but this is changing every day.

In brief: Depends
Most follow a multi-factorial pattern, with about 4% risk of the offspring having some form of defect (not the same one).
Offspring of 2 parents with any form of CHD have about 10% risk of any defect in their children. Some genetic syndromes have associated heart defects , risk would follow the pattern of those syndromes.When questions arise, consulting a geneticist is worthwhile.
