AD familial adult myoconic epilepsy 2 (FAME2) - generalised tonic clonic seizures are a feauture but they are infrequent. Guerrini et al, 2001 - Large Italian kindred -11 aff individuals all had infrequent generalidsed tonic-clonic seizures and 3 also had intractable complex partial seizures. Labuge et al 2002 - 4 generation European family - 8/13 generalised tonic-clonic seizures. De Falco et al, 2003 - 2 Italian families - most patients had infrequent seizures - no variant identified - Madia et al, 2008. De Fusco et al, 2014 - 4 generation Italian family - 5 aff - 4 had generalised tonic clonic seizures and 2 had drug-resistant focal seizures also looked at Guerrini et al 2000 family - all had het delins mutation - haplotype analysis suggested a founder effect, functional studies suggest GOF.
