Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000036670	SCV000060325	uncertain significance	not specified	2012-11-14	criteria provided, single submitter	clinical testing	The Phe4016Tyr variant in RYR2 has not been reported in the literature nor previ ously identified by our laboratory. This variant has been identified in 1/8198 E uropean American chromosomes from a broad population screened by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS). Computational analyses ( biochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide strong support for or against an impact to the protein. In summa ry, additional information is needed to fully assess the clinical significance o f the Phe4016Tyr variant.
GeneDx	RCV000766732	SCV000235192	uncertain significance	not provided	2017-10-20	criteria provided, single submitter	clinical testing	The F4016Y variant has not been published as pathogenic or been reported as benign to our knowledge. The F4016Y variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. The F4016Y variant is located in one of the three hot-spot regions of the RYR2 gene, where the majority of pathogenic missense variants occur (Medeiros-Domingo et al., 2009). Though, F4016Y was observed in 22/125,516 (0.02%) alleles from individuals of European (Non-Finnish) from large population cohorts (Lek et al., 2016).
Illumina Laboratory Services, Illumina	RCV000378772	SCV000356449	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.

Invitae	RCV001093785	SCV000955682	uncertain significance	Catecholaminergic polymorphic ventricular tachycardia 1	2022-05-15	criteria provided, single submitter	clinical testing	This sequence change replaces phenylalanine, which is neutral and non-polar, with tyrosine, which is neutral and polar, at codon 4016 of the RYR2 protein (p.Phe4016Tyr). This variant is present in population databases (rs375021201, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with RYR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 43718). 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 C15"). 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.
Color Diagnostics, LLC DBA Color Health	RCV001182008	SCV001347316	uncertain significance	Cardiomyopathy	2023-03-16	criteria provided, single submitter	clinical testing	This variant is located in the RYR2 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 26/278330 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.
