Living with Ectodermal dysplasia

A group of more than 180 inherited conditions that affect the skin, hair, teeth, nails, and sweat glands.

Understanding Ectodermal dysplasia

Ectodermal dysplasias (ED) are a group of more than 180 conditions that affect tissues that form the skin, sweat glands, hair, teeth, and nails.

Symptoms range from mild to severe. They can include tooth differences, brittle, sparse, or absent hair, nail differences, an inability to sweat (hypohidrosis), and various skin problems. Different types are caused by changes in different genes and are inherited in different ways. Signs show up in the newborn and infant years.

Signs & symptoms

Symptoms vary from person to person. GARD's summary describes these among the common features:

  • Tooth differences
  • Brittle, sparse, or absent hair
  • Nail differences
  • Inability to sweat (hypohidrosis)
  • Skin problems

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    National Foundation for Ectodermal Dysplasias and World Craniofacial Foundation may keep lists of experts for this condition.
