Variant summary

Our verdict is Benign. The variant received -19 ACMG points: 1P and 20B. PP2BP4_StrongBP6_Very_StrongBS1BS2

The NM_001035.3(RYR2):c.2630A>C(p.His877Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000148 in 1,612,868 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 Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H877Y) 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: Benign. The variant received -19 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.

BP4

Computational evidence support a benign effect (MetaRNN=0.022494674).

BP6

Variant 1-237506726-A-C is Benign according to our data. Variant chr1-237506726-A-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 180489.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000105 (16/152270) while in subpopulation AMR AF = 0.00105 (16/15306). AF 95% confidence interval is 0.000655. There are 0 homozygotes in GnomAd4. There are 8 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 16 AD gene.
