The cause is not known.A successful repair may be done immediately postnatally, with a very good chance of survival. It is diagnosed definitively with ultrasound demonstrating a normal umbilical cord insertion in the fetal abdomen.
No. The cases of gastroschisis occurring in progeny of parents who had gastroschisis is extremely rare as to be reportable.
