Answer

Autosomal dominant juvenile myoclonic epilepsy is caused by a mutation in one of a number of genes. Patients report myoclonic jerks, most commonly in the morning, but they can also have both generalized tonic-clonic seizures and absence seizures. The onset of this disorder is typically in late childhood or early adolescence.
