Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PP3_Moderate

The NM_002230.4(JUP):​c.1715G>T​(p.Arg572Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000041 in 1,461,804 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R572Q) has been classified as Likely benign.

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: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The Arg572Leu variant in JUP has not been reported in the literature nor previou sly identified by our laboratory. It has also not been detected in 2 very large and broad populations (European and African American) screened by the NHLBI Exom e Sequencing Project (http://evs.gs.washington.edu/EVS/). This low frequency is consistent with a disease causing role but is insufficient to establish this wit h confidence. The affected amino acid is highly conserved in evolution, suggesti ng that a change would impact the protein. This is consistent with other comput ational analyses (biochemical amino acid properties, AlignGVGD, PolyPhen2, and S IFT) that predict an impact to the protein (their accuracy is unknown). Addition al information is needed to fully assess the clinical significance of the Arg572 Leu variant. -

Significance: Uncertain significance

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 572 of the JUP protein (p.Arg572Leu). This variant is not present in population databases (gnomAD no frequency). 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: 45840). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C15"). 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. -
