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 -1 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=0.22489539).

Collection Method: clinical testing

The c.6910G>A (p.G2304S) alteration is located in exon 43 (coding exon 43) of the RYR1 gene. This alteration results from a G to A substitution at nucleotide position 6910, causing the glycine (G) at amino acid position 2304 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 2304 of the RYR1 protein (p.Gly2304Ser). This variant is present in population databases (rs377080876, gnomAD 0.05%). This missense change has been observed in individual(s) with clinical features of RYR1-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 329056). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RYR1 protein function with a negative predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
