RCV001213373 | SCV001385001 | uncertain significance | Seizures, benign familial infantile, 3; Developmental and epileptic encephalopathy, 11 | 2022-01-13 | 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. 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: "Benign"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 943227). This variant has not been reported in the literature in individuals affected with SCN2A-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 301 of the SCN2A protein (p.Asp301Asn). |

RCV002285456 | SCV002575587 | uncertain significance | not provided | 2023-11-09 | criteria provided, single submitter | clinical testing | Not observed at significant frequency in large population cohorts (gnomAD); Missense variants in this gene are often considered pathogenic (HGMD); In silico analysis supports that this missense variant does not alter protein structure/function; This substitution is predicted to be within the extracellular loop between the S5 and S6 transmembrane segments of the first homologous domain.; Has not been previously published as pathogenic or benign to our knowledge |
