Summaries for Early Myoclonic Encephalopathy

KEGG : 36 Early myoclonic encephalopathy (EME) is a rare malignant epileptic syndrome. The erratic myoclonus with or without focal motor seizures, onset before 3 months of age, and persistent suppression-burst pattern in electroencephalograph (EEG) are accepted as the diagnostic criteria for EME. The pathogenesis of EME is variable, with structural, metabolic, and genetic abnormalities all playing a role. Associated metabolic abnormalities are frequently described. In particular, nonketotic hyperglycinemia has been associated with a large number of cases. The prognosis of EME is poor, with no effective treatment, and children with the condition either die within 1-2 years after birth or survive in a persistent vegetative state.

MalaCards based summary : Early Myoclonic Encephalopathy, also known as myoclonic epilepsy, is related to myoclonic epilepsy of unverricht and lundborg and epilepsy, myoclonic juvenile, and has symptoms including myoclonus, muscle spasticity and myoclonic seizures. An important gene associated with Early Myoclonic Encephalopathy is SLC25A22 (Solute Carrier Family 25 Member 22), and among its related pathways/superpathways are Neuroscience and L1CAM interactions. The drugs Levetiracetam and Ethanol have been mentioned in the context of this disorder. Affiliated tissues include brain, temporal lobe and liver, and related phenotypes are myoclonus and infantile spasms
