About this section

OMIM:46 EIEE2 is an X-linked dominant severe neurologic disorder characterized by onset of seizures in the first months of life... (300672) more...

MalaCards based summary: Epileptic Encephalopathy, Early Infantile, 2, also known as early infantile epileptic encephalopathy, is related to rett syndrome and dravet syndrome, and has symptoms including stereotypic behavior, developmental regression and cognitive impairment. An important gene associated with Epileptic Encephalopathy, Early Infantile, 2 is CDKL5 (cyclin-dependent kinase-like 5), and among its related pathways are L1CAM interactions and Interaction between L1 and Ankyrins. The drug topiramate and the compounds aft-ii and atx-ii have been mentioned in the context of this disorder. Affiliated tissues include eye, and related mouse phenotypes are behavior/neurological and growth/size/body.
