Invitae | RCV000549616 | SCV000647861 | uncertain significance | Brugada syndrome 5 | 2023-03-20 | criteria provided, single submitter | clinical testing | ClinVar contains an entry for this variant (Variation ID: 470182). 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: "Possibly Damaging"; Align-GVGD: "Not Available". The tryptophan amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with SCN1B-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 214 of the SCN1B protein (p.Arg214Trp). |
