Living with Ectodermal dysplasia and immune deficiency

An inherited condition with differences in skin, hair, teeth, and sweating, plus a weakened immune system that leads to frequent infections.

Understanding Ectodermal dysplasia and immune deficiency

Ectodermal dysplasia and immune deficiency (EDA-ID) is a form of ectodermal dysplasia in which immune function is also reduced.

Signs are evident soon after birth. Children have dry or wrinkled skin, sparse hair, missing or small pointed teeth, and a reduced ability to sweat, which can lead to overheating. The immune problems vary, but many children make low levels of antibodies, which makes it hard to fight infections.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Repeated bacterial infections
  • Reduced ability to sweat (hypohidrosis)
  • Sparse hair
  • Cone-shaped teeth
  • Chronic diarrhea
  • Poor weight gain and slow growth

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 allergy and immune system specialists, eye disease specialists, genetic specialists and gum, teeth and mouth 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 Immune Deficiency Foundation may keep lists of experts for this condition.
