Abstract

Inherited epidermolysis bullosa defines a heterogeneous group of genodermatoses characterized by skin and/or mucosa fragility resulting in blistering. The junctional variant (JEB) is associated with mutations affecting the genes expressing the components of the dermo-epidermal junction (DEJ) [1-2]. We report 34 JEB patients with COL17A1 genetic mutations diagnosed in our Center between 1993 and 2019. Medical and biological records were collected with a standardized questionnaire.
