Genes affected
JUP (HGNC:6207): (junction plakoglobin) This gene encodes a major cytoplasmic protein which is the only known constituent common to submembranous plaques of both desmosomes and intermediate junctions. This protein forms distinct complexes with cadherins and desmosomal cadherins and is a member of the catenin family since it contains a distinct repeating amino acid motif called the armadillo repeat. Mutation in this gene has been associated with Naxos disease. Alternative splicing occurs in this gene; however, not all transcripts have been fully described. [provided by RefSeq, Jul 2008]

This sequence change creates a premature translational stop signal (p.Ser182*) in the JUP gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in JUP are known to be pathogenic (PMID: 10902626). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with JUP-related conditions. ClinVar contains an entry for this variant (Variation ID: 857898). For these reasons, this variant has been classified as Pathogenic.
