What is Clouston Syndrome?
Clouston syndrome is a genetic condition that can affects a person's hair, nails, and skin. This condition is just one in a group of over 150 conditions known as ectodermal dysplasias. In these individuals, hair can be sparse, lighter in color, patchy, fragile, and/or absent. Fingernails and toenails can be malformed, small, and/or thickened. Skin on the hands and feet can be thick, and the skin over joints may also be darker in color. Teeth and sweat glands are typically not affected in Clouston syndrome. Not everyone with Clouston syndrome experiences the same signs or symptoms.
