Myoclonic epilepsy of Unverricht and Lundborg is an autosomal recessive disorder characterized by onset of neurodegeneration between 6 and 13 years of age. It is typically progressive in adolescence, with dramatic worsening of myoclonus and ataxia in the first 6 years after onset. The disease stabilises in early adulthood, and myoclonus and ataxia may even improve, and there is minimal to no cognitive decline.
Note the most common causative allele is a dodecamer repeat in the promoter region. Missense variants have been reported, most commonly compound het with the repeat, except for p.Gly4Arg which has been reported in the homozygous state also.
