Why did my child get biliary atresia?
No one knows what causes biliary atresia. About one in 8,000 to 20,000 get this rare disorder. Trying to figure out what causes this problem or how we can improve life with biliary atresia is one of the highest priorities of the physicians caring for children with biliary atresia at The Children’s Hospital of Philadelphia. As far as we know, you did not cause your child to get biliary atresia because of anything you did during pregnancy. Nor do you have a gene that gave your child this problem. Within the same family, it is common for only one child in a pair of identical twins to have this disorder.
