| Invitae | RCV001244722 | SCV001417964 | uncertain significance | Arrhythmogenic right ventricular dysplasia 9 | 2023-03-31 | criteria provided, single submitter | clinical testing | 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. 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. ClinVar contains an entry for this variant (Variation ID: 969385). This variant has not been reported in the literature in individuals affected with PKP2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 579 of the PKP2 protein (p.Cys579Tyr). |

RCV003532920 | SCV004358875 | uncertain significance | Cardiomyopathy | 2022-12-21 | criteria provided, single submitter | clinical testing | This missense variant replaces cysteine with tyrosine at codon 579 of the PKP2 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with PKP2-related disorders in the literature. This variant has not been identified 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. |
