Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3
The NM_001036.6(RYR3):c.9143G>A(p.Arg3048His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000254 in 1,613,538 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. R3048C) has been classified as Uncertain significance.

Epileptic encephalopathy Uncertain:1
This sequence change replaces arginine with histidine at codon 3048 of the RYR3 protein (p.Arg3048His). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and histidine. 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RYR3-related conditions. This variant is present in population databases (rs139568967, ExAC 0.009%). -
