Description

Variant summary: The SCN5A c.2182G>A (p.Val728Ile) variant involves the alteration of a conserved nucleotide located in the Ion transport domain (IPR005821) (InterPro). 2/4 in silico tools predict a benign outcome for this variant (SNPsandGO not captured due to low reliability index). This variant was found in 2/246420 control chromosomes (gnomAD and Garca-Molina_2013) at a frequency of 0.0000081, which does not exceed the estimated maximal expected allele frequency of a pathogenic SCN5A variant (0.0001). This variant was reported in one patient with Brugada syndrome without strong evidence for causality (Garca-Molina_2013). Taken together, this variant is classified as VUS until additional evidence becomes available.
