Variant summary
Our verdict is Benign. The variant received -10 ACMG points: 1P and 11B. PP2BP4_ModerateBP6BS1BS2
The NM_001035.3(RYR2):āc.5294C>Gā(p.Ser1765Cys) variant causes a missense change. The variant allele was found at a frequency of 0.000113 in 1,614,016 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S1765F) has been classified as Uncertain significance.

Variant summary: RYR2 c.5294C>G (p.Ser1765Cys) results in a non-conservative amino acid change located in the Ryanodine receptor junctional solenoid repeat domain (IPR048581) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00018 in 248986 control chromosomes. The observed variant frequency is approximately 5.3-fold of the estimated maximal expected allele frequency for a pathogenic variant in RYR2 causing Catecholaminergic Polymorphic Ventricular Tachycardia phenotype (3.4e-05). c.5294C>G has been reported in the literature in settings of multi-gene panel testing in individuals affected with sudden cardiac death, unexplained cardiac arrest with catecholaminergic polymorphic ventricular tachycardia, hypertrophic cardiomyopathy, arrhythmogenic cardiomyopathy, hot-phase cardiomyopathy, often in the presence of other variants classified as VUS, in all cases without evidence of causality (e.g. Brion_2014, Jimenez-Jaimez_2015, Mademont-Soler_2017, Goudal_2022, Bassetto_2024). These reports do not provide unequivocal conclusions about association of the variant with Catecholaminergic Polymorphic Ventricular Tachycardia. Co-occurrences with other pathogenic variants have been reported including an individual affected with dilated cardiomyopathy (FLNC c.5669-1delG) (e.g. Begay_2016) and an individual affected with arrhythmogenic cardiomyopathy (PKP2 c.775_776insG, p.Glu259Glyfs*77) with the variant not segregating with disease in at least one affected family member (e.g. Robles-Mezcua_2023), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 38414301, 28008423, 24981977, 35819174, 26189708, 28771489, 37510372). ClinVar contains an entry for this variant (Variation ID: 404210). Based on the evidence outlined above, the variant was classified as likely benign. -

Catecholaminergic polymorphic ventricular tachycardia 1 Benign:2
- -
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
Arrhythmogenic right ventricular dysplasia 2 Uncertain:1
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
RYR2-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
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. -
