RCV000038185 | SCV000061852 | likely pathogenic | Arrhythmogenic right ventricular cardiomyopathy | 2010-12-14 | criteria provided, single submitter | clinical testing | The Val587fs variant has not been reported in the literature and has not been pr eviously detected by our laboratory. This variant is predicted to cause a frame shift, which alters the protein's amino acid sequence beginning at codon 587 and leads to a premature stop codon 69 amino acids downstream. This alteration is t hen predicted to lead to a truncated or absent protein (loss of function). Patho genic loss of function variants are common in the PKP2 gene, which makes it high ly likely that the Val587fs is pathogenic. |

RCV001525490 | SCV001735623 | pathogenic | Cardiomyopathy | 2020-05-24 | criteria provided, single submitter | clinical testing | This variant deletes 1 nucleotide in exon 8 of the PKP2 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. To our knowledge, this variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of PKP2 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. |

Ambry Genetics | RCV002408518 | SCV002716618 | pathogenic | Cardiovascular phenotype | 2018-04-12 | criteria provided, single submitter | clinical testing | The c.1759delG pathogenic mutation, located in coding exon 8 of the PKP2 gene, results from a deletion of one nucleotide at nucleotide position 1759, causing a translational frameshift with a predicted alternate stop codon (p.V587Sfs*69). This alteration has been reported in an arrhythmogenic right ventricular cardiomyopathy (ARVC) cohort (Tan BY et al. J Cardiovasc Transl Res, 2010 Dec;3:663-73). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. |
