Hypohidrotic ectodermal dysplasia
Hypohidrotic ectodermal dysplasia is a congenital (present at birth) condition that causes a variety of typically mild complications.
What is hypohidrotic ectodermal dysplasia?
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.
What are the signs and symptoms of hypohidrotic ectodermal dysplasia?
Signs and symptoms of hypohidrotic ectodermal dysplasia include:
Chronic respiratory illness
Chronic sinusitis
Dark circles around a child’s eyes
Depressed nose
Dry eyes
Dry mouth and nasal passages
Eczema (very dry, scaly skin)
Hypodontia (missing teeth)
Hypotrichosis (fine, sparse hair)
Skin that peels unusually
Small, narrow jawline
Small, pointy teeth
Hypohidrosis (trouble sweating to cool down the body)
Teeth that are slow to erupt (emerge through the gum)
Trouble regulating body temperature (can lead to being irritable in warm environments or unexplained fevers)
What are the causes of hypohidrotic ectodermal dysplasia?
A gene mutation causes hypohidrotic ectodermal dysplasia and it is passed down in families (hereditary).
