| Invitae | RCV001057002 | SCV001221470 | pathogenic | Arrhythmogenic right ventricular dysplasia 9 | 2023-08-14 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 852405). 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 creates a premature translational stop signal (p.Val51Glufs*34) in the PKP2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PKP2 are known to be pathogenic (PMID: 15489853, 23911551). |

RCV001057002 | SCV002557334 | pathogenic | Arrhythmogenic right ventricular dysplasia 9 | 2022-02-02 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with arrhythmogenic right ventricular dysplasia 9 (ARVD9; MIM#609040). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0112 - The condition associated with this gene has incomplete penetrance (PMID: 17010805, PMID: 23183494). (I) 0115 - Variants in this gene are known to have variable expressivity (PMID: 17010805, PMID: 23183494). (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction). (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0701 - Other variants predicted to result in NMD comparable to the one identified in this case have very strong previous evidence for pathogenicity (ClinVar, DECIPHER). (SP) 0803 - This variant has limited previous evidence of pathogenicity in an unrelated individual. This variant has been reported as pathogenic in ClinVar. (SP) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
