Description

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with COL7A1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Pro2649Argfs*35) in the COL7A1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in COL7A1 are known to be pathogenic (PMID: 16971478).
