Recessive dystrophic epidermolysis bullosa (RDEB) is a severe inherited blistering disease caused by the absence of type VII collagen. Patients with RDEB develop large, severely painful blisters and open wounds from minor trauma to their skin. We are screening RDEB subjects to determine additional characteristics of patients who survive to adulthood.

Inclusion Criteria:1. Clinical diagnosis of RDEB by local dermatologist. 2. 18 years of age or more and willing to give consent. Exclusion Criteria:1. Medical instability limiting ability to travel to Stanford University Medical Center.
