Description

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 1391 of the SCN5A protein (p.Gly1391Arg). This variant is present in population databases (rs780405533, gnomAD 0.006%). This missense change has been observed in individual(s) with long QT syndrome (PMID: 30244407, 31737537). ClinVar contains an entry for this variant (Variation ID: 201589). 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 disruptive. 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.
