How common is anencephaly?
About one out of every 5,000 to 10,000 babies is born with anencephaly, and the condition affects baby girls more often than boys. Most pregnancies with anencephaly end in miscarriage or stillbirth. Women who have had another child with an NTD, such as spina bifida, have a higher risk of conceiving a child with anencephaly.
