Variant summary
Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM2PP2PP3_Moderate
The NM_001035.3(RYR2):c.2401C>A(p.Arg801Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,120 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. R801C) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 03, 2019 | 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with RYR2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with serine at codon 801 of the RYR2 protein (p.Arg801Ser). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and serine. - |
