| Ambry Genetics | RCV000618719 | SCV000735864 | uncertain significance | Cardiovascular phenotype | 2017-05-15 | criteria provided, single submitter | clinical testing | The p.G330E variant (also known as c.989G>A), located in coding exon 3 of the PKP2 gene, results from a G to A substitution at nucleotide position 989. The glycine at codon 330 is replaced by glutamic acid, an amino acid with some similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV004594085 | SCV005086327 | uncertain significance | Arrhythmogenic right ventricular dysplasia 9 | 2023-07-17 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3B. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with arrhythmogenic right ventricular cardiomyopathy (ARVC) (MIM#609040). On the other hand, dominant-negative is the proposed mechanism for missense variants in this gene (PMID: 23183494, 24967631). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0112 - The condition associated with this gene has incomplete penetrance (PMID: 17010805, 23183494). (I) 0115 - Variants in this gene are known to have variable expressivity. (PMID: 17010805, 23183494). (I) 0200 - Variant is predicted to result in a missense amino acid change from glycine to glutamic acid. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0809 - Previous evidence of pathogenicity for this variant is inconclusive. It has been classified as a VUS by a diagnostic laboratory in ClinVar. (I) 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 |
