Ectodermal dysplasias

Definition

Ectodermal dysplasias is a group of conditions in which there is abnormal development of the skin, hair, nails, teeth, or sweat glands.

Alternative Names

Anhidrotic ectodermal dysplasia; Christ-Siemens-Touraine syndrome; Anondontia; Incontinentia pigmenti

Causes

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.

Symptoms

People with ectodermal dysplasia have a lack of sweat glands. This means they may not sweat or sweat less than normal.

In children with the disease, their bodies may have a problem controlling fevers. When the skin cannot sweat, it is hard for the body to control temperature properly. So even a mild illness can cause a very high fever.

Adults with the disease can't tolerate a warm environment. Air conditioning and other measures are needed to keep a normal body temperature.

Depending on which genes are affected, other symptoms may include:
