Familial cases of patent ductus arteriosus (PDA) have been recorded, but a genetic cause has not been determined. In infants born at term who have a persistent patent ductus arteriosus (PDA), the recurrence rate among siblings is 5%. Some early evidence suggests that as many as one third of cases are caused by a recessive trait labeled PDA1, located on chromosome 12, at least in some populations.
