Invitae | RCV000469974 | SCV000545172 | uncertain significance | Brugada syndrome 5 | 2024-01-16 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 187 of the SCN1B protein (p.Arg187Cys). This variant is present in population databases (rs758654948, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SCN1B-related conditions. ClinVar contains an entry for this variant (Variation ID: 406500). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. |

RCV000614197 | SCV000729876 | likely benign | not specified | 2018-01-05 | criteria provided, single submitter | clinical testing | This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. |
