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 was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.013612628).

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 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 GnomAdExome4. There are 35 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

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. -
