AEBP1 and gastroschisis: Mouse models that showed gastroschisis-like phenotypes spurred interest in genes such as BMP1 and AEBP1. In 2001, a BMP1 gene null deletion mouse model [8] showed a gastroschisis-like condition; however, a retrospective study was unable to identify any mutations on the BMP1 gene in a cohort of 11 gastroschisis patients [22].
