Definition:

Familial infantile myoclonic epilepsy (FIME) is a rare autosomal recessive idiopathic epilepsy. Idiopathic epilepsies are a group of disorders characterized by recurrent seizures in the absence of detectable brain lesions or metabolic abnormalities. Recently, mutations in TBC1D24, an ARF6-interacting protein, have been described as the cause of FIME. The main recognized function of ARF6 in the nervous system is the regulation of dendritic branching, spine formation, and axonal extension.
