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]

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: JUP c.567C>T alters a non-conserved nucleotide resulting in a synonymous change. 4/4 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0003 in 247354 control chromosomes, predominantly at a frequency of 0.0026 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 104 fold of the estimated maximal expected allele frequency for a pathogenic variant in JUP causing Cardiomyopathy phenotype (2.5e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. To our knowledge, no occurrence of c.567C>T in individuals affected with Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. Co-occurrences with other pathogenic variant(s) have been reported (TTR c.424G>A, p.Val142Ile) at our laboratory providing supporting evidence for a benign role. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. -

Phosphorus, Inc.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This synonymous variant has occurred in GnomAD with a total MAF of 0.0305% and with the highest MAF of 0.2576% in the African population. This position is not conserved. In silico splicing algorithm predicted no impact on splicing, but no functional studies were performed to confirm this prediction. This variant NM_002230.4(JUP):c.567C>T (p.Val189=) is present in the ClinVar database (ID: 45854). The variant has not occurred in the literature in association with the disease. Considering that the variant has a relatively high frequency in a subpopulation, it has been classified as Likely Benign. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

p.Val189Val in Exon 04 of JUP: This variant is not expected to have clinical sig nificance because it does not alter an amino acid residue, is not located within the splice consensus sequence. It has been identified in 0.2% (7/3734) of Afric an American chromosomes from a broad population by the NHLBI Exome Sequencing Pr oject (http://evs.gs.washington.edu/EVS; dbSNP rs35297577). -

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

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. -
