Labcorp Genetics (formerly Invitae), Labcorp RCV000640633 SCV000762227 pathogenic Seizures, benign familial infantile, 3; Developmental and epileptic encephalopathy, 11 2020-02-07 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with SCN2A-related conditions. ClinVar contains an entry for this variant (Variation ID: 533497). Loss-of-function variants in SCN2A are known to be pathogenic (PMID: 22495306, 23020937, 24650168). For these reasons, this variant has been classified as Pathogenic. This sequence change creates a premature translational stop signal (p.Trp1424Leufs*10) in the SCN2A gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency).
