What are some other examples of birth defects?

• Duodenal atresia, an obstruction in the small intestine. It can cause polyhydramios (extra fluid around the baby in pregnancy), which can increase the risk of preterm birth. It is sometimes associated with other genetic syndromes.
• Dandy walker malformation, an abnormal development of the posterior fossa (a space in your baby’s skull) and cerebellum (a section of the brain). This birth defect can cause a variety of problems.
• Limb defects, which happen when the fetal amnion (the inner lining of the amniotic sack) wraps around parts of the fetus (like a finger or foot).
