RCV001059772 | SCV001224418 | uncertain significance | Arrhythmogenic right ventricular dysplasia 10 | 2022-06-14 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 854675). This variant has not been reported in the literature in individuals affected with DSG2-related conditions. This variant is present in population databases (rs375740419, gnomAD 0.01%). This sequence change replaces lysine, which is basic and polar, with methionine, which is neutral and non-polar, at codon 369 of the DSG2 protein (p.Lys369Met). |

Ambry Genetics | RCV002429681 | SCV002741363 | uncertain significance | Cardiovascular phenotype | 2021-05-05 | criteria provided, single submitter | clinical testing | The p.K369M variant (also known as c.1106A>T), located in coding exon 9 of the DSG2 gene, results from an A to T substitution at nucleotide position 1106. The lysine at codon 369 is replaced by methionine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV004000111 | SCV004827855 | uncertain significance | Arrhythmogenic right ventricular cardiomyopathy | 2023-12-01 | criteria provided, single submitter | clinical testing | This missense variant replaces lysine with methionine at codon 369 of the DSG2 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 reported for this variant. This variant has not been reported in individuals affected with DSG2-related disorders in the literature. This variant has been identified in 3/280826 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. |
