1-237651485-C-G

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 3P and 2B. PM2PP2BP4BP6

The NM_001035.3(RYR2):​c.7808C>G​(p.Ala2603Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000192 in 1,564,582 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A2603T) has been classified as Likely benign.

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: Uncertain_significance. The variant received 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
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=0.3946829).
BP6
Variant 1-237651485-C-G is Benign according to our data. Variant chr1-237651485-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 1760710.
