Living with Junctional epidermolysis bullosa

A group of inherited skin conditions in which the skin is so fragile that it blisters easily, sometimes with blisters inside the mouth and digestive tract.

Understanding Junctional epidermolysis bullosa

Junctional epidermolysis bullosa (JEB) is a major form of epidermolysis bullosa, a group of genetic conditions with very fragile, easily blistering skin.

Blisters and areas of skin loss form after minor rubbing or injury. There are two main types: generalized severe (formerly Herlitz) and generalized intermediate (formerly non-Herlitz). In the severe type, blistering starts at birth or early infancy over large areas and can affect the mouth and digestive tract, making eating hard. Children may be undernourished and grow slowly. Other effects can include scarring, nail and tooth enamel differences, joint contractures, and hair loss.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Its summary describes these features:

  • Fragile skin that blisters easily
  • Skin erosions after minor injury
  • Blisters in the mouth and digestive tract
  • Trouble eating and slow growth
  • Nail changes and tooth enamel differences
  • Weak, hoarse cry and breathing difficulty in severe type

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
