Dr. Thomas Riney
Pediatrics 38 years experience
Low: If parent has chd, chance of child is less than 2%.
Dr. James Ferguson
Pediatrics 47 years experience
Varies: Most CHD is polygenicm meaning it travels on multiple genes/chromosomes.Their offspring have about 4% risk of any (not just the same) CHD. If the other parent has any form of CHD it jumps to about 10%. There are some forms of CHD that are associated with gene based dominant or recessive syndromes.For these it depends on the syndrome.A geneticist can provide a better number with more history/data.
