Ambry Genetics | RCV000621019 | SCV000736149 | uncertain significance | Cardiovascular phenotype | 2017-12-07 | criteria provided, single submitter | clinical testing | The p.S4407N variant (also known as c.13220G>A), located in coding exon 90 of the RYR2 gene, results from a G to A substitution at nucleotide position 13220. The serine at codon 4407 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species, and asparagine is the reference amino acid in other 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. |

RCV000772659 | SCV000905918 | uncertain significance | Cardiomyopathy | 2022-11-15 | criteria provided, single submitter | clinical testing | This missense variant replaces serine with asparagine at codon 4407 of the RYR2 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 RYR2-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. |

RCV001101827 | SCV001258468 | uncertain significance | Arrhythmogenic right ventricular dysplasia 2 | 2018-01-13 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. |

RCV001101828 | SCV001258469 | likely benign | Catecholaminergic polymorphic ventricular tachycardia 1 | 2018-01-13 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. |

RCV004002654 | SCV004824184 | uncertain significance | Catecholaminergic polymorphic ventricular tachycardia | 2023-04-03 | criteria provided, single submitter | clinical testing | This missense variant replaces serine with asparagine at codon 4407 of the RYR2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. 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). 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. |
