It is characterized by mechanically fragile skin that readily blister. Most of the more severe subtypes are associated with clinically significant extracutaneous complications. Some subtypes may lead to death, even in early infancy. There are four major types of EB: EB simplex, junctional EB, dystrophic EB, and Kindler syndrome.
