RCV000218353 | SCV000272306 | uncertain significance | not specified | 2016-01-26 | criteria provided, single submitter | clinical testing | The p.Arg490Gln variant in PKP2 has not been previously reported in individuals with cardiomyopathy, but has been identified in 4/13418 South Asian chromosomes and 2/6462 African chromosomes by the Exome Aggregation Consortium (ExAC, http:/ /exac.broadinstitute.org; dbSNP rs369518480). Computational prediction tools and conservation analysis suggest that this variant may not impact the protein, tho ugh this information is not predictive enough to rule out pathogenicity. In summ ary, the clinical significance of the p.Arg490Gln variant is uncertain. |
Invitae | RCV000640002 | SCV000761589 | uncertain significance | Arrhythmogenic right ventricular dysplasia 9 | 2023-12-15 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 490 of the PKP2 protein (p.Arg490Gln). This variant is present in population databases (rs369518480, gnomAD 0.02%). This missense change has been observed in individual(s) with sudden unexplained death (PMID: 29247119). ClinVar contains an entry for this variant (Variation ID: 229143). 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. |

RCV001175623 | SCV001339292 | uncertain significance | Cardiomyopathy | 2023-02-28 | criteria provided, single submitter | clinical testing | This missense variant replaces arginine with glutamine at codon 490 of the PKP2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been performed for this variant. This variant has been reported in a sudden unexplained deaths cohort (PMID: 29247119). This variant has been identified in 16/261928 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
Ambry Genetics | RCV002390585 | SCV002701585 | likely benign | Cardiovascular phenotype | 2020-12-14 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: 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. |
