Overview
Inherited epidermolysis bullosa (EB) comprises rare genetic disorders characterized by skin and mucosal fragility due to mutations in genes encoding structural proteins critical for epidermal-dermal adhesion. Classified into four main types (simplex, junctional, dystrophic, Kindler syndrome), EB severity ranges from localized blistering to life-threatening complications involving internal organs. Diagnosis relies on genetic testing, immunofluorescence mapping, and electron microscopy. Management is multidisciplinary, emphasizing wound care, infection prevention, nutritional support, and emerging therapies like gene correction.
Therapies
Supportive care: Nonadhesive dressings, pain management, and nutritional interventions [6][12].
Advanced therapies: FDA-approved beremagene geperpavec (B-VEC) gene therapy for dystrophic EB; investigational approaches include protein/cell-based therapies and drug repurposing (e.g., JAK/IL-13 inhibitors) [3][8][18].
