Fig. 2From: Novel and de novo mutations in pediatric refractory epilepsySchematic representation of the mutations in subunit alpha of sodium channel type 1 (SCN1A) in our study. SCN1A alpha unit has four domains (I–IV), each domain includes 6 transmembrane segments (S1–S6). Purple circle = mutation; AEDs, anti-epileptic drugs. The position of mutations in SCN1A is approximate and is according to reference transcript NM_001165963.Back to article page
