Abstract

Genetic testing is the gold standard for diagnosing different epidermolysis bullosa (EB) subtypes; however, testing rates are low. We conducted a pilot study to test feasibility of a novel, home-based registry that involved patients with EB submitting self-reported clinical symptoms using secure, online surveys (REDCap) and submitting buccal swabs for exome sequencing of EB-related genes (GeneDx). In total, 50?EB participants were enrolled, with an average age of 17?years and an average distance of 198?miles from EB specialty centers. All buccal swabs (N?=?24) provided sufficient DNA for sequencing without causing mucosal trauma and 80% of participants were found to have pathogenic variants in COL7A1, the gene mutated in DEB. Participants with recessive dystrophic EB (RDEB) reported a higher prevalence of esophageal dilations (65.7% vs. 0%, p?=?.009) and mitten deformities of the feet (57.1% vs. 0%, p?=?.047) compared to non-RDEB participants.
