RCV003509148 | SCV004301958 | uncertain significance | Brugada syndrome 5 | 2023-07-09 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine, which is neutral and polar, with lysine, which is basic and polar, at codon 190 of the SCN1B protein (p.Gln190Lys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SCN1B-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. |
