Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM2PM5PP2PP3_Moderate

The ENST00000366574.7(RYR2):​c.1396C>A​(p.Pro466Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000274 in 1,461,334 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P466A) 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_pathogenic. Variant got 7 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr1-237454494-C-G is described in Lovd as [Pathogenic].
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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.907
