Variant chr1-237784571-T-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PM2PP2BS1

The NM_001035.3(RYR2):c.12859T>A(p.Tyr4287Asn) variant causes a missense change. The variant allele was found at a frequency of 0.00000205 in 1,461,682 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. Y4287H) 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). The gene has 195 curated pathogenic missense variants (we use a threshold of 10). The gene has 55 curated benign missense variants. GenCC has associacion of the gene with hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, catecholaminergic polymorphic ventricular tachycardia 1, arrhythmogenic right ventricular dysplasia 2, catecholaminergic polymorphic ventricular tachycardia.

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.00000205 (3/1461682) while in subpopulation AMR AF= 0.0000671 (3/44724). AF 95% confidence interval is 0.0000178. There are 0 homozygotes in gnomad4_exome. There are 1 alleles in male gnomad4_exome subpopulation. Median coverage is 33. This position pass quality control queck.
