Living with Epidermolysis bullosa simplex with anodontia/hypodontia

A rare form of EB simplex with injury-triggered blisters plus hearing loss, hair loss, missing teeth, and nail changes.

Understanding Epidermolysis bullosa simplex with anodontia/hypodontia

Epidermolysis bullosa simplex with anodontia/hypodontia is a rare form of EB simplex with blisters plus tooth, hair, nail, and hearing differences.

It is seen in newborns and infants. Along with blisters after injury, GARD lists hearing impairment, hair loss, missing or fewer teeth (hypodontia), and nail changes. Pale skin patches (vitiligo-like) not related to blisters have also been described.

Signs & symptoms

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

  • Skin blisters
  • Fewer teeth than usual (tooth agenesis)
  • Tooth enamel problems
  • Hair loss or sparse scalp hair
  • Fingernail and toenail changes
  • Nearsightedness (myopia)

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 eye disease specialists, genetic specialists, gum, teeth and mouth 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
