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]

Variant classified as Uncertain Significance - Favor Benign. The p.Val528Ile var iant in JUP has not been previously reported in individuals with cardiomyopathy, but has been identified in 0.1% (6/7780) African chromosomes by the Exome Aggre gation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs368271628). Val ine (Val) at position 528 is conserved in mammals but not in evolutionarily dist ant species and 5 fish species carry an isoleucine (Ile), supporting that this c hange may be tolerated. Additional computational prediction tools suggest that t his variant may not impact the protein, though this information is not predictiv e enough to rule out pathogenicity. In summary, while the clinical significance of the p.Val528Ile variant is uncertain, these data suggest that it is more like ly to be benign. -

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. -
