GeneDx RCV000524047 SCV000617047 uncertain significance not provided 2016-05-11 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the JUP gene. The G92C variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The G92C variant was not observed in approximately 6,500 individuals of European and African American ancestry in an external variant database, indicating it is not a common benign variant in these populations. The G92C variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Furthermore, in silico analysis predicts this variant is probably damaging to the protein structure/function. However, this substitution occurs at a position that is not conserved across species. Therefore, based on the currently available information, it is unclear whether this variant is pathogenic or rare benign.
Ambry Genetics RCV000617807 SCV000736419 uncertain significance Cardiovascular phenotype 2017-05-25 criteria provided, single submitter clinical testing The p.G92C variant (also known as c.274G>T), located in coding exon 2 of the JUP gene, results from a G to T substitution at nucleotide position 274. The glycine at codon 92 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Invitae RCV000645198 SCV000766940 uncertain significance Naxos disease; Arrhythmogenic right ventricular dysplasia 12 2022-01-17 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 92 of the JUP protein (p.Gly92Cys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. 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: 449201). 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: "Possibly Damaging"; Align-GVGD: "Class C0"). 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.
