Note: Some of the variants listed here involve more than one base, so we chose to title this page "Polymorphisms" rather than "Single nucleotide polymorphisms (SNPs)"
Exon-intron boundaries were deduced from rat Scn1a using NCBI's Basic Local Alignment Tool (BLAST). An effort was made to reference the first report of the mutation. Topological data are taken from the secondary structure suggested in Escayg and colleagues in 2000. AA: amino acid, D1/S2 (example): Domain 1/Transmembrane region 2 (topology code indexes "in" and "ex" denote internal and external loop, respectively), NA: nucleic acid.
