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 replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 190 of the JUP protein (p.Val190Leu). This variant is present in population databases (rs370143312, gnomAD 0.003%). 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: 581839). 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. -
