Labcorp Genetics (formerly Invitae), Labcorp RCV001226876 SCV001399204 uncertain significance Brugada syndrome 5 2019-07-14 criteria provided, single submitter clinical testing 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with SCN1B-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with aspartic acid at codon 88 of the SCN1B protein (p.Gly88Asp). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and aspartic acid.
