ClinVar
Submissions by phenotype
not specified    Uncertain:1 
The c.6226G>A (p.V2076M) alteration is located in exon 40 (coding exon 40) of the RYR3 gene. This alteration results from a G to A substitution at nucleotide position 6226, causing the valine (V) at amino acid position 2076 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Epileptic encephalopathy    Uncertain:1 
This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 2076 of the RYR3 protein (p.Val2076Met). This variant is present in population databases (rs760123258, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with RYR3-related conditions. ClinVar contains an entry for this variant (Variation ID: 530971). 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: "Probably Damaging"; Align-GVGD: "Class C15"). 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. -
