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]

Labcorp Genetics (formerly Invitae), Labcorp
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 177 of the JUP protein (p.Arg177Gln). This variant is present in population databases (rs371481933, gnomAD 0.006%). This missense change has been observed in individual(s) with arrhythmogenic right ventricular cardiomyopathy (PMID: 27532257). ClinVar contains an entry for this variant (Variation ID: 178044). 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 tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The Arg177Gln variant in JUP has not been reported in individuals with cardiomyo pathy, but has been identified in 2/8600 of European American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/). Computation al analyses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhe n2, and SIFT) suggest that the Arg177Gln variant may not impact the protein, tho ugh this information is not predictive enough to rule out pathogenicity. Additio nal information is needed to fully assess the clinical significance of the Arg17 7Gln variant. -

Cardiovascular phenotype Benign:1

Ambry Genetics
Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
