Living with Generalized dominant dystrophic epidermolysis bullosa

An inherited skin condition in which the skin blisters very easily; it is one of the milder forms of epidermolysis bullosa.

Understanding Generalized dominant dystrophic epidermolysis bullosa

Generalized dominant dystrophic epidermolysis bullosa is a type of inherited skin condition in which skin blisters very easily.

It is one of the milder forms of epidermolysis bullosa (EB), though severity varies. Blisters may be present at birth but usually appear in early childhood, often at the knees, ankles, elbows, and knuckles. In adulthood, blisters usually become less frequent and scars fade.

Signs & symptoms

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

  • Easy skin blistering
  • Fragile skin
  • Scarring of the skin
  • Small white bumps (milia)
  • Poorly formed or missing nails
  • Constipation, tooth decay, and swallowing 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. Consider genetic testing

    Changes in COL7A1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    DEBRA of America may keep lists of experts for this condition.
