Labcorp Genetics (formerly Invitae), Labcorp RCV001366945 SCV001563270 uncertain significance Naxos disease; Arrhythmogenic right ventricular dysplasia 12 2024-12-27 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 497 of the JUP protein (p.Leu497Arg). This variant is present in population databases (no rsID available, gnomAD 0.005%). 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: 1057877). 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 disruptive. 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.
Ambry Genetics RCV002395830 SCV002698737 uncertain significance Cardiovascular phenotype 2021-11-09 criteria provided, single submitter clinical testing The p.L497R variant (also known as c.1490T>G), located in coding exon 7 of the JUP gene, results from a T to G substitution at nucleotide position 1490. The leucine at codon 497 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
