ClinVar
Submissions by phenotype
not specified Uncertain:1
The c.4540C>T (p.R1514C) alteration is located in exon 34 (coding exon 34) of the RYR3 gene. This alteration results from a C to T substitution at nucleotide position 4540, causing the arginine (R) at amino acid position 1514 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Epileptic encephalopathy Uncertain:1
Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 1514 of the RYR3 protein (p.Arg1514Cys). This variant is present in population databases (rs375458327, gnomAD 0.02%). 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: 571924). 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. 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. -
