Neuberg Centre For Genomic Medicine, NCGM RCV003340794 SCV004047517 uncertain significance Generalized epilepsy with febrile seizures plus, type 2 criteria provided, single submitter clinical testing The missense variant c.1033T>A (p.Cys345Ser) in SCN1A gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Cys345Ser variant is novel (not in any individuals) in gnomAD Exomes and 1000 Genomes. The amino acid Cys at position 345 is changed to a Ser changing protein sequence and it might alter its composition and physico-chemical properties. The amino acid change p.Cys345Ser in SCN1A is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance.
