Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3
The NM_001036.6(RYR3):c.14098G>A(p.Glu4700Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000113 in 1,614,084 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. E4700Q) has been classified as Uncertain significance.

Submissions by phenotype
not specified Uncertain:1
The c.14098G>A (p.E4700K) alteration is located in exon 99 (coding exon 99) of the RYR3 gene. This alteration results from a G to A substitution at nucleotide position 14098, causing the glutamic acid (E) at amino acid position 4700 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Epileptic encephalopathy Uncertain:1
This sequence change replaces glutamic acid with lysine at codon 4700 of the RYR3 protein (p.Glu4700Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. This variant is present in population databases (rs201221837, ExAC 0.01%). This variant has not been reported in the literature in individuals with RYR3-related conditions. ClinVar contains an entry for this variant (Variation ID: 579781). 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: "Benign"; Align-GVGD: "Class C0"). 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. -
