Genes affected
RYR1 (HGNC:10483): (ryanodine receptor 1) This gene encodes a ryanodine receptor found in skeletal muscle. The encoded protein functions as a calcium release channel in the sarcoplasmic reticulum but also serves to connect the sarcoplasmic reticulum and transverse tubule. Mutations in this gene are associated with malignant hyperthermia susceptibility, central core disease, and minicore myopathy with external ophthalmoplegia. Alternatively spliced transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PP2
Missense variant in the RYR1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 212 curated pathogenic missense variants (we use a threshold of 10). The gene has 94 curated benign missense variants. Gene score misZ: 1.918 (below the threshold of 3.09). Trascript score misZ: 3.9788 (above the threshold of 3.09). GenCC associations: The gene is linked to King-Denborough syndrome, congenital multicore myopathy with external ophthalmoplegia, autosomal recessive centronuclear myopathy, RYR1-related myopathy, lethal multiple pterygium syndrome, malignant hyperthermia of anesthesia, benign Samaritan congenital myopathy, malignant hyperthermia, susceptibility to, 1, congenital myopathy with myasthenic-like onset, central core myopathy.
BP4
Computational evidence support a benign effect (MetaRNN=0.013612628).
BS1
Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000628 (91/1448360) while in subpopulation AMR AF= 0.00211 (90/42712). AF 95% confidence interval is 0.00176. There are 0 homozygotes in gnomad4_exome. There are 35 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

RYR1-related disorder Uncertain:1Benign:1

PreventionGenetics, part of Exact Sciences
Significance: Uncertain significance
Review Status: no assertion criteria provided
Collection Method: clinical testing

The RYR1 c.13498G>A variant is predicted to result in the amino acid substitution p.Glu4500Lys. This variant was observed in the heterozygous state in a patient with rhabdomyolysis; however, pathogenicity was not established (internal data; Supp. Table 2 Kushnir et al 2020. PubMed ID: 32236737). This variant is reported in 0.23% of alleles in individuals of Latino descent in gnomAD, which is likely too frequent to be a primary cause of autosomal dominant disorders. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
