Summaries for Epileptic Encephalopathy, Early Infantile, 12

NIH Rare Diseases : 54 Early Infantile Epileptic Encephalopathy type 12 (EIEE12) is an extremely rare nervous system disorder. Infants with EIEE12 develop very frequent epileptic seizures. Seizures present within the first days to months of life. Seizures may trigger eye rolling, eyelid fluttering, lip smacking, drooling, bluish coloring around the mouth, limpness, or muscle stiffening (particularly those in his or her back, legs, and arms). The seizures associated with this disease are difficult to treat and the syndrome is severely progressive. EIEE12 occurs when a child inherits two mutations in the PLCB1 gene (one from each parent). EIEE12 is inherited in an autosomal recessive fashion. 

MalaCards based summary : Epileptic Encephalopathy, Early Infantile, 12, also known as early infantile epileptic encephalopathy 12, is related to early infantile epileptic encephalopathy, and has symptoms including muscle spasticity An important gene associated with Epileptic Encephalopathy, Early Infantile, 12 is PLCB1 (Phospholipase C Beta 1). Affiliated tissues include eye, and related phenotypes are spasticity and hyperreflexia

Disease Ontology : 12 An early infantile epileptic encephalopathy that has material basis in homozygous or compound heterozygous mutation in the PLCB1 gene on chromosome 20p12.3.

UniProtKB/Swiss-Prot : 76 Epileptic encephalopathy, early infantile, 12: A form of epilepsy characterized by frequent tonic seizures or spasms beginning in infancy with a specific EEG finding of suppression-burst patterns, characterized by high-voltage bursts alternating with almost flat suppression phases. Patients may progress to West syndrome, which is characterized by tonic spasms with clustering, arrest of psychomotor development, and hypsarrhythmia on EEG.
