Invitae | RCV000463174 | SCV000545171 | uncertain significance | Brugada syndrome 5 | 2023-12-06 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 163 of the SCN1B protein (p.Arg163Gln). This variant is present in population databases (rs199685662, gnomAD 0.02%). 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: 406499). 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 glutamine 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. |

The authors identified additional variants in this family, including compound heterozygous variants in the PIGN gene that were expected to explain the familial phenotype (Fleming et al., 2016); Reported in ClinVar as a variant of uncertain significance (ClinVar Variant ID# 403733; Landrum et al., 2016); In silico analysis, which includes splice predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 26394714) |
