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 made for transcript

Verdict is Benign. Variant got -11 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.22).
BP6
Variant 1-237680447-T-C is Benign according to our data. Variant chr1-237680447-T-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 463648.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=3, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0000213 (31/1455654) while in subpopulation NFE AF= 0.000028 (31/1107588). AF 95% confidence interval is 0.0000201. There are 0 homozygotes in gnomad4_exome. There are 22 alleles in male gnomad4_exome subpopulation. Median coverage is 28. This position pass quality control queck.
BS2
High AC in GnomAdExome4 at 31 AD gene.
