Abstract

Background: Ectodermal dysplasia (ED) is a rare hereditary disorder characterized by congenital defect involving two or more of the ectodermal structures, which include the skin, hair, nails, teeth, and sweat glands. The two most common forms of the disease are hypohidrotic/anhidrotic ED and hidrotic ED. They are caused by the mutations of several genes. Even though usually transmitted as x-linked recessive trait, in about 70 percent of cases, carrier females of hypohidrotic ectodermal dysplasia experience some features of the condition whose presentation varies from very mild to very severe.
