Description

Has been reported in individuals referred for indications unrelated to cardiomyopathy/arrhythmia (PMID: 27153395, 26746457); Reported in association with LQTS and atrial fibrillation in the published literature (PMID: 19716085, 21051419, 22685113, 24144883, 24606995, 26213684); Functional studies suggest that this variant does not significantly affect sodium channel function (PMID: 21051419, 26213684); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 24144883, 24606995, 22685113, 31983221, 21051419, 25051102, 22581653, 25649125, 28150151, 26746457, 26213684, 28988457, 31737537, 30847666, 34803699, 23631430, 25904541, 37652022, 19716085, 27153395)

Description

This sequence change replaces phenylalanine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 1596 of the SCN5A protein (p.Phe1596Ile). This variant is present in population databases (rs199473278, gnomAD 0.02%). This missense change has been observed in individual(s) with clinical features of SCN5A-related conditions (PMID: 9716085, 21051419, 25051102, 26213684, 30847666, 31737537, 31983221). ClinVar contains an entry for this variant (Variation ID: 67924). 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. Experimental studies have shown that this missense change does not substantially affect SCN5A function (PMID: 21051419, 26213684). 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.
