Living with Junctional epidermolysis bullosa with pyloric atresia

A severe form of junctional epidermolysis bullosa with blisters at birth and a blocked outlet of the stomach.

Understanding Junctional epidermolysis bullosa with pyloric atresia

Junctional epidermolysis bullosa with pyloric atresia is a severe form with blistering at birth and a blocked stomach outlet (pylorus).

Blistering is widespread at birth. The pylorus, the opening from the stomach to the intestine, is not formed or open (pyloric atresia), and other parts of the digestive tract are rarely affected. GARD also lists kidney and bladder differences and weak tooth enamel. It starts during pregnancy or in newborns.

Signs & symptoms

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

  • Blistering skin
  • Blocked stomach outlet (pyloric atresia)
  • Bloated belly and vomiting
  • Kidney and bladder differences
  • Blood in urine
  • Weak tooth enamel

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, gum, teeth and mouth specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in ITGB4 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
