Human Gene Set: HP_EPILEPTIC_SPASM


Standard name HP_EPILEPTIC_SPASM
Systematic name M37766
Brief description Epileptic spasm
Full description or abstract A sudden flexion, extension, or mixed extension-flexion of predominantly proximal and truncal muscles that is usually more sustained than a myoclonic movement but not as sustained as a tonic seizure. Limited forms may occur: Grimacing, head nodding, or subtle eye movements. Epileptic spasms frequently occur in clusters. Infantile spasms are the best known form, but spasms can occur at all ages [HPO_CONTRIBUTOR:jalbers, PMID:28276060]
