Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000036746	SCV000060401	uncertain significance	not specified	2013-02-05	criteria provided, single submitter	clinical testing	The c.4596+4C>T variant in RYR2 has not been reported in any individuals with ca techolaminergic polymorphic ventricular tachycardia (CPVT) or arrhythmogenic rig ht ventricular cardiomyopathy (ARVC) but has been identified in 1 individual wit h right ventricular dilation and ventricular tachycardia (LMM data). It has also been identified in 5/271950 chromosomes by gnomAD (http://gnomad.broadinstitute .org). This variant is located in the 5' splice region. Computational tools do n ot predict a splicing impact, though this information is not predictive enough t o rule out pathogenicity. In summary, the clinical significance of this variant is uncertain. ACMG/AMP Criteria applied: PM2, BP4.
Invitae	RCV002513421	SCV000957294	uncertain significance	Catecholaminergic polymorphic ventricular tachycardia 1	2024-01-18	criteria provided, single submitter	clinical testing	This sequence change falls in intron 34 of the RYR2 gene. It does not directly change the encoded amino acid sequence of the RYR2 protein. It affects a nucleotide within the consensus splice site. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. 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: 43785). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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	RCV003531926	SCV004360599	uncertain significance	Cardiomyopathy	2023-01-12	criteria provided, single submitter	clinical testing	This variant causes a C to T nucleotide substitution at the +4 position of intron 34 of the RYR2 gene. 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.
