GeneDx RCV000188962 SCV000242593 pathogenic not provided 2016-06-29 criteria provided, single submitter clinical testing The Arg1525Stop variant in the SCN1A gene has been reported in several individuals with SCN1A-related disorders (Kearney et al., 2006; Harkin et al., 2007). This variant is predicted to cause loss of normal protein function through protein truncation or nonsense-mediated mRNA decay. This variant has been seen apparently mosaic.
Invitae RCV001382664 SCV001581559 pathogenic Early infantile epileptic encephalopathy with suppression bursts 2020-10-08 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg1525*) in the SCN1A gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with SCN1A-related conditions (PMID: 16458823, 28079314, 27465585). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 189911). Loss-of-function variants in SCN1A are known to be pathogenic (PMID: 17347258, 18930999). For these reasons, this variant has been classified as Pathogenic.
