Green List (high evidence)

AD generalised epilepsy with febrile seizures. Lerche et al 2001 & Schubert et al, 2014 - 5 generation German family where 18 individuals experienced early onset/febrile seizures - 6 indivdiuals with the core phenotype and carried the variant. The rest = atypical phenotype and thought to be affected - did not carry the variant. All patients seizure free later in childhood. Weber at al 2008 - 4 generation German family where 8 individuals had seizures - all seizure free later in childhood. Moller et al, 2016 - 216 patient epilepsy cohort - 4 de novo STX1B variants detected.
