Recessive dystrophic epidermolysis bullosa (RDEB) is one of the most severe nonsyndromic forms, which is caused by biallelic loss‐of‐function variants in the collagen type VII gene (COL7A1, OMIM accession number: 120,120) (Wagner et al., 2010). This evidence concerns the gene COL7A1 and recessive dystrophic epidermolysis bullosa.
