Submissions by phenotype
Cardiomyopathy Uncertain:1
This missense variant replaces aspartic acid with asparagine at codon 3733 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 cardiovascular disorders in the literature. This variant has been identified in 1/248642 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. -
Catecholaminergic polymorphic ventricular tachycardia 1 Uncertain:1
This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 3733 of the RYR2 protein (p.Asp3733Asn). This variant is present in population databases (rs760307737, gnomAD 0.0009%). This missense change has been observed in individual(s) with clinical features of RYR2-related conditions (PMID: 32152366). ClinVar contains an entry for this variant (Variation ID: 220973). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RYR2 protein function with a negative predictive value of 95%. 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. -
Cardiovascular phenotype Benign:1
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
