Variant summary
Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4
The NM_000540.3(RYR1):c.8843C>G(p.Ser2948Trp) variant causes a missense change. The variant allele was found at a frequency of 0.0000123 in 1,460,736 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. S2948S) has been classified as Likely benign.

RYR1-related disorder Uncertain:1
This sequence change replaces serine, which is neutral and polar, with tryptophan, which is neutral and slightly polar, at codon 2948 of the RYR1 protein (p.Ser2948Trp). This variant is present in population databases (rs759514075, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with RYR1-related conditions. ClinVar contains an entry for this variant (Variation ID: 580917). 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. -
