p.Arg1213Ter (CGA>TGA): c.3637 C>T in exon 18 of the SCN1A gene (NM_001165963.1) The R1213X nonsense mutation in the SCN1A gene has been reported previously in a monozygotic twins with severe myoclonic epilepsy of infancy (Fujiwara et al., 2003) and in a patient with intractable epilepsy (Wang et al., 2012). This mutation is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Therefore, the presence of the R1213X mutation is consistent with a diagnosis of a SCN1A-related disorder. The variant is found in EPILEPSY panel(s).
