Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PM2PP2BP4_ModerateBP6_Moderate

The NM_001035.3(RYR2):​c.2029T>A​(p.Leu677Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000248 in 1,613,910 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict 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. L677V) 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 made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RYR2. . Gene score misZ 5.7809 (greater than the threshold 3.09). Trascript score misZ 6.4158 (greater than threshold 3.09). GenCC has associacion of gene with hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, catecholaminergic polymorphic ventricular tachycardia 1, arrhythmogenic right ventricular dysplasia 2, catecholaminergic polymorphic ventricular tachycardia.
BP4
Computational evidence support a benign effect (MetaRNN=0.20628783).
BP6
Variant 1-237496578-T-A is Benign according to our data. Variant chr1-237496578-T-A is described in ClinVar as [Likely_benign]. Clinvar id is 570238.Status of the report is criteria_provided_single_submitter, 1 stars.
