Description

This sequence change creates a premature translational stop signal (p.Thr31Glnfs*14) in the DSG2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DSG2 are known to be pathogenic (PMID: 17105751, 31386562). This variant is present in population databases (rs758282201, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with DSG2-related conditions. ClinVar contains an entry for this variant (Variation ID: 422697). For these reasons, this variant has been classified as Pathogenic.
