RCV002027583 | SCV002311028 | uncertain significance | Brugada syndrome 5 | 2023-08-17 | 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 output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The proline amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 1517756). This variant has not been reported in the literature in individuals affected with SCN1B-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 240 of the SCN1B protein (p.Ser240Pro). |
