Because anencephaly is caused by abnormalities of the neural tube, it is classified as a neural tube defect. Because the neural tube fails to close properly, the developing brain and spinal cord are exposed to the amniotic fluid that surrounds the fetus in the womb.
Vitamin B12 is also an important receptor in the folate biopathway such that studies have shown deficiency in vitamin B12 contributes to risk of NTDs as well. Importantly, a deficiency of folate itself does not cause neural tube defects.
