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]

Likely pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 28, 2023This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 301 of the JUP protein (p.Glu301Gly). This variant is present in population databases (rs782058451, gnomAD 0.004%). This missense change has been observed in individuals with clinical features of autosomal dominant JUP-related conditions and/or Naxos disease (PMID: 24884844, 28098346, 33673806). ClinVar contains an entry for this variant (Variation ID: 222662). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJan 26, 2016Variant classified as Uncertain Significance - Favor Pathogenic. The p.Glu301Gly variant in JUP has been reported in the homozygous state in 1 individual with N axos disease (Tradakis 2014), and has also been identified in 1/66640 European c hromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute .org; dbSNP rs782058451). Computational prediction tools and conservation analys is do not provide strong support for or against an impact to the protein. In sum mary, while there is some suspicion for a pathogenic role, the clinical signific ance of the p.Glu301Gly variant is uncertain. -
