Labcorp Genetics (formerly Invitae), Labcorp RCV001942334 SCV002230859 pathogenic Early infantile epileptic encephalopathy with suppression bursts 2021-01-17 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts the C-terminus of the SCN1A protein. Other variant(s) that disrupt this region (p.Arg1912*) have been determined to be pathogenic (PMID: 14738421, 23195492, 20522430, Invitae). This suggests that variants that disrupt this region of the protein are likely to be causative of disease. This variant has been observed in individual(s) with Dravet syndrome (PMID: 29188601). This variant is a gross deletion of the genomic region encompassing exon(s) 12-26 of the SCN1A gene. The 5' boundary is likely confined to intron 11. The 3' end of this event is unknown as it extends through the termination codon beyond the assayed region for this gene and may encompass additional genes. While this deletion is not anticipated to lead to nonsense mediated decay, it is expected to alter mRNA translation or result in a truncated protein product.
