RCV000443545 | SCV000535561 | uncertain significance | not provided | 2018-12-31 | criteria provided, single submitter | clinical testing | A variant of uncertain significance has been identified in the JUP gene. The P677L variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. This variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The P677L variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species and in silico analysis suggests that this variant is probably damaging to the protein structure/function. However, this variant lacks observation in a significant number of affected individuals, segregation data, and functional evidence, which would further clarify its pathogenicity. |
| Ambry Genetics | RCV000620043 | SCV000736340 | likely benign | Cardiovascular phenotype | 2021-10-27 | criteria provided, single submitter | 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. |

RCV002480325 | SCV003246461 | uncertain significance | Naxos disease; Arrhythmogenic right ventricular dysplasia 12 | 2025-02-02 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 677 of the JUP protein (p.Pro677Leu). This variant is present in population databases (rs782622653, gnomAD 0.01%). 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: 392309). 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. |
