    What are the genetic changes related to abdominal wall defect ?
    ### Response:
    No genetic mutations are known to cause an abdominal wall defect. Multiple genetic and environmental factors likely influence the development of this disorder. Omphalocele and gastroschisis are caused by different errors in fetal development.  Omphalocele occurs during an error in digestive tract development.
