GeneDx RCV000154842 SCV000235387 benign not specified 2017-03-17 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Four of five in-silico tools predict a damaging effect of the variant on protein function. The observed variant frequency within African control individuals in the gnomAD database is approximately 216 fold of the estimated maximal expected allele frequency for a pathogenic variant in SCN5A causing Cardiomyopathy phenotype (2.5e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African origin. The variant, c.1852C>T, has been reported in the literature in individuals affected with sudden unexplained death (SUD)( Wang_2014 ), Brugada syndrome (Amin_2009), atrial fibrillation (Darbar_2008), and long QT syndrome (Tester_2005). These report(s) do not provide unequivocal conclusions about association of the variant with Cardiomyopathy, Brugada syndrome, atrial fibrillation, Long QT, or SCD. At least one publication reports experimental evidence evaluating an impact on protein function. These results showed no damaging effect of this variant (Yang_2002). Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant as benign (2x) and likely benign (2x). Based on the evidence outlined above, the variant was classified as Benign.
