How is an atrial septal defect genetically passed on?

An atrial septal defect (ASD) can have a genetic component, as it is often associated with certain genetic syndromes, such as Down syndrome or Turner syndrome. While most ASDs occur sporadically without a clear inheritance pattern, some studies suggest that a familial tendency may exist, where the condition can be passed down through families. Genetic mutations or chromosomal abnormalities may contribute to the development of ASDs, but the exact mechanisms and inheritance patterns can vary. Overall, the genetic basis of ASDs is complex and not fully understood.
