Labcorp Genetics (formerly Invitae), Labcorp RCV005184597 SCV005817303 uncertain significance Brugada syndrome 5 2024-02-21 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 193 of the SCN1B protein (p.Glu193Lys). This variant is present in population databases (no rsID available, gnomAD 0.001%). This missense change has been observed in individual(s) with SCN1B-related conditions (PMID: 30847666). 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.
