Labcorp Genetics (formerly Invitae), Labcorp RCV001228966 SCV001401396 uncertain significance RYR1-related disorder 2022-07-25 criteria provided, single submitter clinical testing 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. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 956206). This variant has not been reported in the literature in individuals affected with RYR1-related conditions. This variant is present in population databases (rs772803714, gnomAD 0.003%). This sequence change replaces glycine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 2266 of the RYR1 protein (p.Gly2266Cys). This variant also falls at the last nucleotide of exon 41, which is part of the consensus splice site for this exon.
