Hypohidrotic ectodermal dysplasia is a congenital (present at birth) condition that causes a variety of typically mild complications.
A child with hypohidrotic ectodermal dysplasia usually has trouble regulating their body temperature, is missing teeth and has fine, thin hair. Children with this hereditary (passed down in families) condition also have a distinctive facial appearance. Despite these differences, people with hypohidrotic ectodermal dysplasia typically have normal intelligence and development, and no major problems.

Signs and symptoms of hypohidrotic ectodermal dysplasia include:
