Ectodermal dysplasia is a genetic condition that affects the development of certain tissues in the body, particularly those derived from the ectoderm layer during embryonic development. This can lead to abnormalities in skin, hair, nails, teeth, and sweat glands. Individuals with this condition may experience sparse hair, missing teeth, and reduced ability to sweat. The condition is often inherited and can vary in severity and symptoms among affected individuals. There are different types of ectodermal dysplasia, each with unique features. Treatment typically focuses on managing symptoms, such as dental care for missing teeth and skin care for dryness.
