Introduction
CSTB (Cystatin B) is a Protein Coding gene. Diseases associated with CSTB include Myoclonic Epilepsy Of Unverricht And Lundborg and Unverricht-Lundborg Syndrome. Among its related pathways are Innate Immune System. Gene Ontology (GO) annotations related to this gene include endopeptidase inhibitor activity. An important paralog of this gene is CSTA.

Involvement in disease
Epilepsy, progressive myoclonic 1 (EPM1):
A form of progressive myoclonic epilepsy, a clinically and genetically heterogeneous group of disorders defined by the combination of action and reflex myoclonus, other types of epileptic seizures, and progressive neurodegeneration and neurocognitive impairment. EPM1 is an autosomal recessive form characterized by severe, stimulus-sensitive myoclonus and tonic-clonic seizures. The onset, occurring between 6 and 13 years of age, is characterized by convulsions. Myoclonus begins 1 to 5 years later. The twitchings occur predominantly in the proximal muscles of the extremities and are bilaterally symmetrical, although asynchronous. At first small, they become late in the clinical course so violent that the victim is thrown to the floor. Mental deterioration and eventually dementia develop.
