Abstract

The blistering disease Epidermolysis bullosa acquisita is a genetic/autoimmune disorder derivingfrom alterations of the human protein Collagen alpha-1(VII) chain (CO7A1). Exposure to severe acuterespiratory syndrome coronavirus 2 (SARS-CoV-2) promotes a wide variety of autoimmune diseases andmight be a risk factor for Epidermolysis bullosa acquisita; in order to further our understanding of thelink between this blistering disease and SARS-CoV-2, this study analyzes the peptide-sharing betweenCO7A1 and SARS-CoV-2 proteome. Results indicate a high level of molecular mimicry between CO7A1and SARS-CoV-2 and hCoV-229E, and hCoV-NL63, thus suggesting a potential role of COVID-19 as arisk factor for Epidermolysis bullosa acquisita.
