La maladie d’Unverricht-Lundborg (MUL) est une épilepsie myoclonique caractérisée par la survenue, chez le grand enfant ou le jeune adolescent, de crises. BAFME must be differentiated from epilepsy syndromes with prominent myoclonus features. Patients may easily be misdiagnosed as having juvenile myoclonic. Juvenile myoclonic epilepsy (JME), also known as Janz syndrome, is a fairly common form of generalized epilepsy of presumed genetic origin representing.

Diagnosis is based on clinical and juvenilf findings.
Linkage analysis of juvenile myoclonic epilepsy and microsatellite loci spanning epilepeie cM of human chromosome 6p in 19 nuclear pedigrees provides no evidence for a susceptibility locus in this region. However a number of quantitative MRI studies have reported focal or regional myocponique of the subcortical and cortical grey matter, particularly the thalamus and frontal cortex, in JME patients. Genetic counseling is possible when a family member has the disease and presymptomatic diagnosis may be done in young patients from families mapped on any of the 3 loci, based on electrophysiological findings.
