Ectodermal dysplasias is a group of conditions in which there is abnormal development of the skin, hair, nails, teeth, or sweat glands.
Anhidrotic ectodermal dysplasia; Christ-Siemens-Touraine syndrome; Anondontia; Incontinentia pigmenti
There are many different types of ectodermal dysplasias. Each type of dysplasia is caused by specific mutations in certain genes. Dysplasia means abnormal development of cells or tissues. The most common form of ectodermal dysplasia usually affects men. Other forms of the disease affect men and women equally.
People with ectodermal dysplasia may not sweat or may have decreased sweating because of a lack of sweat glands.
In children with the disease, their bodies may have a problem controlling fevers. Even a mild illness can produce an extremely high fever, because the skin cannot sweat and control temperature properly.
Affected adults are unable to tolerate a warm environment and need special measures to keep a normal body temperature.
Depending on which genes are affected, other symptoms may include:
