Living with Epidermolysis bullosa simplex 1D, generalized, intermediate or severe, autosomal recessive

A rare inherited form of EB simplex with blisters starting in newborns, mostly on the hands and feet or all over.

Understanding Epidermolysis bullosa simplex 1D, generalized, intermediate or severe, autosomal recessive

Epidermolysis bullosa simplex 1D is a rare inherited form of EB simplex with blistering that starts in the newborn period.

Blistering may be widespread or mostly on the hands and feet. Scarring and nail changes are common, along with thickened skin on the palms and soles. Other effects can include anemia, slow growth, mouth blisters, cavities, and constipation. For some, blistering lasts throughout life.

Signs & symptoms

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

  • Skin blisters
  • Blisters in the mouth
  • Skin erosions
  • Thickened skin on palms and soles
  • Nail changes (fingernails and toenails)
  • Blisters on the palms and soles

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 KRT14 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.
