Genetics Home Reference : ²⁶ Juvenile myoclonic epilepsy is a condition characterized by recurrent seizures (epilepsy). This condition begins in childhood or adolescence, usually between ages 12 and 18, and lasts into adulthood. The most common type of seizure in people with this condition is myoclonic seizures, which cause rapid, uncontrolled muscle jerks. People with this condition may also have generalized tonic-clonic seizures (also known as grand mal seizures), which cause muscle rigidity, convulsions, and loss of consciousness. Sometimes, affected individuals have absence seizures, which cause loss of consciousness for a short period that appears as a staring spell. Typically, people with juvenile myoclonic epilepsy develop the characteristic myoclonic seizures in adolescence, then develop generalized tonic-clonic seizures a few years later. Although seizures can happen at any time, they occur most commonly in the morning, shortly after awakening. Seizures can be triggered by a lack of sleep, extreme tiredness, stress, or alcohol consumption.

MalaCards based summary : Epilepsy, Idiopathic Generalized 10, also known as juvenile myoclonic epilepsy, is related to epilepsy, myoclonic juvenile and juvenile absence epilepsy, and has symptoms including myoclonus and absence seizures. An important gene associated with Epilepsy, Idiopathic Generalized 10 is GABRD (Gamma-Aminobutyric Acid Type A Receptor Delta Subunit), and among its related pathways/superpathways are Circadian entrainment and Transmission across Chemical Synapses. Affiliated tissues include brain, eye and cortex, and related phenotypes are eeg with polyspike wave complexes and morning myoclonic jerks

Disease Ontology : ¹² A adolescence-adult electroclinical syndrome that is characterized by brief, involuntary twitching of a muscle or a group of muscles (myoclonus) early in the morning with onset between 12 and 18 years.

NIH Rare Diseases : ⁵⁴ Juvenile myoclonic epilepsy is an epilepsy syndrome characterized by myoclonic jerks (quick jerks of the arms or legs), generalized tonic-clonic seizures (GTCSs), and sometimes, absence seizures. The seizures of juvenile myoclonic epilepsy often occur when people first awaken in the morning. Seizures can be triggered by lack of sleep, extreme fatigue, stress, or alcohol consumption. Onset typically occurs around adolesence in otherwise healthy children. The causes of juvenile myoclonic epilepsy are very complex and not completely understood. Mutations in one of several genes, including the GABRA1 and the EFHC1 genes, can cause or increase susceptibility to this condition. Although patients usually require lifelong treatment with anticonvulsants, their overall prognosis is generally good.

OMIM : ⁵⁸ Idiopathic generalized epilepsy (EIG) is a broad term that encompasses several common seizure phenotypes, classically including childhood absence epilepsy (CAE, ECA), juvenile absence epilepsy (JAE), and juvenile myoclonic epilepsy (JME, EJM) (Commission on Classification and Terminology of the International League Against Epilepsy, 1989). Generalized epilepsy with febrile seizures plus (GEFS+) shows phenotypic overlap with IGE, and includes patients with early-onset febrile seizures who later develop various types of febrile and afebrile seizures, such as those observed in EIG (summary by Singh et al., 1999). For a general phenotypic description and a discussion of genetic heterogeneity of EIG, see 600669. For a general phenotypic description and a discussion of genetic heterogeneity of GEFS+, see 604233. For a general phenotypic description and a discussion of genetic heterogeneity of EJM, see 254770. (613060)

UniProtKB/Swiss-Prot : ⁷⁶ Epilepsy, idiopathic generalized 10: A disorder characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Generalized seizures arise diffusely and simultaneously from both hemispheres of the brain. Generalized epilepsy with febrile seizures plus 5: A rare autosomal dominant, familial condition with incomplete penetrance and large intrafamilial variability. Patients display febrile seizures persisting sometimes beyond the age of 6 years and/or a variety of afebrile seizure types. This disease combines febrile seizures, generalized seizures often precipitated by fever at age 6 years or more, and partial seizures, with a variable degree of severity. Juvenile myoclonic epilepsy 7: A subtype of idiopathic generalized epilepsy. Patients have afebrile seizures only, with onset in adolescence (rather than in childhood) and myoclonic jerks which usually occur after awakening and are triggered by sleep deprivation and fatigue.
