Can Apert syndrome occur more than once in a family?
Most cases of Apert syndrome are sporadic. This means that there is no family history of the syndrome and it is unlikely to occur again in another pregnancy. However if you have Apert syndrome, you have a 1 in 2 or a 50% chance of having a child with Apert syndrome for each pregnancy. This is because Apert syndrome is inherited in an autosomal dominant manner.
