Invitae RCV000547184 SCV000637027 uncertain significance Brugada syndrome 2018-11-29 criteria provided, single submitter clinical testing This sequence change replaces tyrosine with aspartic acid at codon 158 of the SCN10A protein (p.Tyr158Asp). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and aspartic acid. This variant is present in population databases (rs202192818, ExAC 0.05%), and has an allele count higher than expected for a pathogenic variant (PMID: 28166811). This variant has been reported in individuals affected with atrial fibrillation and arrhythmogenic right ventricular dysplasia/cardiomyopathy (PMID: 25053638, 25085921, 26733327). All reported individuals also carried another change (c.2441G>A, p.Arg814His) that was shown to be in cis in at least three individuals (PMID: 25053638, 26733327). ClinVar contains an entry for this variant (Variation ID: 463260). Experimental studies in vitro have shown that this missense change generates a peak current that is 2 times larger than that of wild type (PMID: 25053638). 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.
