Abstract
Only a few familial cases of gastroschisis have been reported. Consequently, the risk of a recurrence has been thought to be very small. In a population‐based study of gastroschisis that included an extended pedigree of all probands, 6 (4.7%) out of 127 families had more than one affected relative. The relationships of the affected were: sib, half‐sib (2), first cousin, second cousin once removed, and great uncle. Sib recurrence was 3.5%. Our results suggest that pregnancies occurring in a family with a history of gastroschisis may be at higher risk of recurrence than previously thought.
