Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 3P and 5B. PP2PP3_ModerateBS1_SupportingBS2

The ENST00000366574.7(RYR2):​c.4829G>A​(p.Arg1610Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000161 in 1,613,280 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1610P) has been classified as Uncertain significance.

Genes affected
RYR2 (HGNC:10484): (ryanodine receptor 2) This gene encodes a ryanodine receptor found in cardiac muscle sarcoplasmic reticulum. The encoded protein is one of the components of a calcium channel, composed of a tetramer of the ryanodine receptor proteins and a tetramer of FK506 binding protein 1B proteins, that supplies calcium to cardiac muscle. Mutations in this gene are associated with stress-induced polymorphic ventricular tachycardia and arrhythmogenic right ventricular dysplasia. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

PP2
Missense variant in the RYR2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 195 curated pathogenic missense variants (we use a threshold of 10). The gene has 55 curated benign missense variants. Gene score misZ: 5.7809 (above the threshold of 3.09). Trascript score misZ: 6.4158 (above the threshold of 3.09). GenCC associations: The gene is linked to hypertrophic cardiomyopathy, catecholaminergic polymorphic ventricular tachycardia 1, catecholaminergic polymorphic ventricular tachycardia, arrhythmogenic right ventricular dysplasia 2, arrhythmogenic right ventricular cardiomyopathy.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.842
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000329 (5/152114) while in subpopulation SAS AF = 0.000208 (1/4816). AF 95% confidence interval is 0.0000197. There are 0 homozygotes in GnomAd4. There are 4 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAd4 at 5 AD gene.
