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]

The p.R176L variant (also known as c.527G>T), located in coding exon 3 of the JUP gene, results from a G to T substitution at nucleotide position 527. The arginine at codon 176 is replaced by leucine, an amino acid with dissimilar properties. Another alteration affecting the same amino acid, p.R176W (c.526C>T), has been reported in association with cardiomyopathy (Kostareva A et al. PLoS ONE Sep;11:e0163362). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is not present in population databases (gnomAD no frequency). 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with JUP-related conditions. This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 176 of the JUP protein (p.Arg176Leu). -
