Vitamin A Embryopathy can lead to which of the following defects?

• A. Neural tube defects
• B. Microtia
• C. Spina bifida
• D. Congenital heart defects only

Answer: (B)

Vitamin A Embryopathy is associated with teratogenic effects when there is excessive exposure to vitamin A during early pregnancy. One of the most notable defects linked to Vitamin A Embryopathy is microtia, which is characterized by underdeveloped or malformed ears. This condition exemplifies how teratogens can impact specific anatomical structures during critical periods of embryonic development. While neural tube defects and spina bifida are seen as consequences of folic acid deficiency, they are not primarily linked to vitamin A excess. Congenital heart defects can arise from a variety of factors, but the direct association with Vitamin A is less precise than with microtia. Thus, microtia is a more definitive manifestation of Vitamin A Embryopathy, highlighting its role in the development of the ear structures during embryogenesis.
