ClinVar
Submissions by phenotype
not specified Uncertain:1
The p.Asn2188Lys variant in RYR1 has not been previously reported in individuals with myopathy, but has been identified in 1/111628 European chromosomes by the Genome Aggregation Database (gnomAD; http://gnomad.broadinstitute.org; dbSNP rs3 73570763). This variant has not been previously reported in the literature, but has been reported in ClinVar (VariantID:93282). Computational prediction tools a nd conservation analysis suggest that this variant may impact the protein, thoug h this information is not predictive enough to determine pathogenicity. In summa ry, the clinical significance of the p.Asn2188Lys variant is uncertain. -
Malignant hyperthermia, susceptibility to, 1 Uncertain:1
This missense variant replaces asparagine with lysine at codon 2188 of the RYR1 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with RYR1-related disorders in the literature. This variant has been identified in 1/250936 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
RYR1-related disorder Uncertain:1
This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 2188 of the RYR1 protein (p.Asn2188Lys). This variant is present in population databases (rs373570763, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with RYR1-related conditions. ClinVar contains an entry for this variant (Variation ID: 93282). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt RYR1 protein function with a positive predictive value of 80%. 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. -
