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 -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.43).

BP6

Variant 1-237783871-G-A is Benign according to our data. Variant chr1-237783871-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 43719.

BP7

Synonymous conserved (PhyloP=0.37 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00116 (176/152334) while in subpopulation NFE AF = 0.00213 (145/68022). AF 95% confidence interval is 0.00185. There are 0 homozygotes in GnomAd4. There are 89 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 176 AD gene.
