Description

This sequence change replaces arginine with proline at codon 190 of the SCN5A protein (p.Arg190Pro). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and proline. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with clinical features of Brugada syndrome (Invitae). 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 disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant disrupts the p.Arg190 amino acid residue in SCN5A. Other variant(s) that disrupt this residue have been observed in individuals with SCN5A-related conditions (PMID: 21908450, 17905336), which suggests that this may be a clinically significant amino acid residue. 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.
