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 summary: The JUP c.1172G>A (p.Ser391Asn) variant involves the alteration of a non-conserved nucleotide. 3/3 in silico tools predict a benign outcome for this variant. This variant was found in 29/122542 control chromosomes at a frequency of 0.0002367, which is approximately 24 times the estimated maximal expected allele frequency of a pathogenic JUP variant (0.00001), suggesting this variant is likely a benign polymorphism. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases/clinical diagnostic laboratories. It has been classified as a likely benign by one clinical laboratory in ClinVar. One internal sample carrying this variant also carried a potentially pathogenic variant SCN5A c.5350G>A (p.E1784K) (classified as pathogenic by multiple labs and databases in ClinVar), further supporting the benign outcome. Taken together, this variant is classified as Benign. -

JUP NM_002230.2 exon 8 p.Ser391Asn (c.1172G>A): This variant has not been reported in the literature but is present in 0.2% (27/10354) of Ashkenazi Jewish alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/17-39919560-C-T). This variant is present in ClinVar (Variation ID:191672). This variant amino acid Asparagine (Asn) is present in 4 species and is not well conserved among evolutionarily distant species; this suggests that this variant may not impact the protein. Additional computational prediction tools do not suggest an impact. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

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. -
