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]

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.89).

BP6

Variant 1-237496595-A-G is Benign according to our data. Variant chr1-237496595-A-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 43755.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-4.03 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00622 (948/152290) while in subpopulation AFR AF = 0.0214 (888/41556). AF 95% confidence interval is 0.0202. There are 11 homozygotes in GnomAd4. There are 458 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 948 AD gene.
