There are many different types of ectodermal dysplasia.
Many gene defects can cause ectodermal dysplasias. 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.
Other symptoms include:
Abnormal or missing teeth, or fewer than normal number of teeth
Call for an appointment with your health care provider if your child shows symptoms of this disorder.
If you have a family history of ectodermal dysplasia and you are planning to have children, genetic counseling is recommended. In many cases it is possible to diagnose ectodermal dysplasia while the baby is still in the womb.
