RCV002016522 | SCV002298087 | uncertain significance | RYR1-related disorder | 2022-09-01 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 4390 of the RYR1 protein (p.Glu4390Lys). This variant is not present in population databases (gnomAD no frequency). 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: 1509002). 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 not expected to disrupt RYR1 protein function. 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. |

Ambry Genetics | RCV002545546 | SCV003602584 | uncertain significance | Inborn genetic diseases | 2022-02-02 | criteria provided, single submitter | clinical testing | The c.13168G>A (p.E4390K) alteration is located in exon 91 (coding exon 91) of the RYR1 gene. This alteration results from a G to A substitution at nucleotide position 13168, causing the glutamic acid (E) at amino acid position 4390 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
