What are the main symptoms of Clouston Syndrome?
Clouston syndrome is a genetic condition that can affect a person's hair, nails, and skin. It is a form of ectodermal dysplasia. Hair can be sparse, lighter in color, patchy, fragile, and/or absent. Fingernails and toenails can also be malformed, small, and/or thickened. Skin on the hands and feet can be thick, and skin over joints may be darker in color. Teeth and sweat glands are typically not affected. Not everyone with Clouston syndrome experience the same signs or symptoms.
