Variant summary
Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_000540.3(RYR1):c.14167C>A(p.Arg4723Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,878 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R4723H) has been classified as Likely benign.

RYR1-related disorder Uncertain:1
This variant is present in population databases (rs200473035, gnomAD 0.003%). This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 4723 of the RYR1 protein (p.Arg4723Ser). This variant has not been reported in the literature in individuals affected with RYR1-related conditions. 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). -
