Color Diagnostics, LLC DBA Color Health RCV001180207 SCV001345077 uncertain significance Cardiomyopathy 2019-06-19 criteria provided, single submitter clinical testing This variant is located in the intron 9 splice donor region of the RYR2 gene. Computational splicing tools are inconclusive regarding the impact of this variant on RNA splicing. To our knowledge, functional assays have not been performed for this variant nor has this variant 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). 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.
Invitae RCV002558946 SCV001407834 uncertain significance Catecholaminergic polymorphic ventricular tachycardia 1 2024-01-24 criteria provided, single submitter clinical testing This sequence change falls in intron 9 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. This variant is not present in population databases (gnomAD no frequency). 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: 921062). 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 may disrupt the consensus splice site. 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.
