What causes Aplasia cutis congenita ?
What causes aplasia cutis congenita? There is no one cause for all cases of aplasia cutis congenita. The condition is thought to be multifactorial, which means that several factors likely interact to cause the condition. Factors that may contribute include genetic factors; teratogens (exposures during pregnancy that can harm a developing fetus) such as methimazole, carbimazole, misoprostol, and valproic acid; compromised vasculature to the skin; and trauma. Some cases may represent an incomplete or unusual form of a neural tube defect. Familial cases of aplasia cutis congenita have been reported. Cases that appear to be genetic may be inherited in an autosomal dominant or autosomal recessive manner.
