Unverricht–Lundborg disease (abbreviated ULD or EPM1) is the most common form of an uncommon group of genetic epilepsy disorders called the progressive myoclonus epilepsies. It is caused due to a mutation in the cystatin B gene (CSTB). The disease is named after Heinrich Unverricht who first described it in 1891 and Herman Bernhard Lundborg who researched it in greater detail in 1903.
