| Invitae | RCV002552562 | SCV001208463 | uncertain significance | Catecholaminergic polymorphic ventricular tachycardia 1 | 2022-07-19 | 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 842265). This variant has not been reported in the literature in individuals affected with RYR2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 3232 of the RYR2 protein (p.Pro3232Ser). |

RCV003532355 | SCV004360744 | uncertain significance | Cardiomyopathy | 2022-01-05 | criteria provided, single submitter | clinical testing | This missense variant replaces proline with serine at codon 3232 of 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 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. |
