AEDs = antiepileptic drugs; C = Chromosome; DNM1 = Dynamin 1; KCNQ2 = Potassium voltage-gated channel subfamily Q member 2; PCDH19 = Protocadherin 19; SCN1A = Sodium voltage-gated channel alpha subunit 1; SCN2A = Sodium voltage-gated channel alpha subunit 2; SCN9A = Sodium voltage-gated channel alpha subunit 9; TSC2 = Tuberous Sclerosis Complex 2. *Due to rarity of some of the genetic mutations, descriptive statistics for positive mutations are not segregated by cannabis use history to maintain participant confidentiality.
