Ectodermal Dysplasia

Versión en español
Ectodermal dysplasias (ED) are disorders that affect the skin, sweat glands, hair, teeth, and nails. Some individuals with ED may also have cleft lip and/or palate. ED can additionally cause problems with the immune system as well as hearing and vision.

More than 180 specific types of this condition have been identified.

Ectodermal dysplasias occur when the outer layer of tissue (ectoderm) of the embryo does not develop normally. If two or more body structures derived from the ectoderm are affected, a person is considered to have ED.

ED is a rare disease, defined in the U.S. as a condition that affects fewer than 200,000 people.
