Center for Genomics, Ann and Robert H. Lurie Children's Hospital of Chicago RCV000768076 SCV000898948 uncertain significance Migraine, familial hemiplegic, 3; Severe myoclonic epilepsy in infancy; Generalized epilepsy with febrile seizures plus, type 2 2017-11-02 criteria provided, single submitter clinical testing SCN1A NM_001165963.1 exon 11 p.Asn601= (c.1803C>T): This variant has not been reported in the literature but is present in 4/15302 African alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs139403702). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. Of note, this variant is a silent variant and does not change the amino acid, reducing the probability that this variant is disease causing. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain.
