Labcorp Genetics (formerly Invitae), Labcorp RCV003109794 SCV003791795 pathogenic Seizures, benign familial infantile, 3; Developmental and epileptic encephalopathy, 11 2022-05-24 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the SCN2A protein in which other variant(s) (p.Met1501Val) have been determined to be pathogenic (PMID: 29933521; Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This variant has not been reported in the literature in individuals affected with SCN2A-related conditions. This variant results in the deletion of part of exon 25 (c.4495_4552-2727del) of the SCN2A gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in SCN2A are known to be pathogenic (PMID: 28379373).
