Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1PM2PP5_Moderate
The NM_001099404.2(SCN5A):c.2597C>A(p.Ser866Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. S866S) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 20, 2023 | This sequence change creates a premature translational stop signal (p.Ser866*) in the SCN5A gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SCN5A are known to be pathogenic (PMID: 20129283, 22789973). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SCN5A-related conditions. For these reasons, this variant has been classified as Pathogenic. - |
