Summaries for Stxbp1 Encephalopathy with Epilepsy

NIH Rare Diseases : 53 Early infantile epileptic encephalopathy 4 (EIEE4) is a form of early infantile epileptic encephalopathy, which refers to a group of neurological conditions characterized by severe seizures beginning in infancy. EIEE4, specifically, is often associated with partial complex or tonic-clonic seizures, although other seizure types have been reported. Other signs and symptoms may include intellectual disability, reduced muscle tone (hypotonia), hypsarrhythmia (an irregular pattern seen on EEG), dyskinesia (involuntary movement of the body), and spastic di- or quadriplegia. EIEE4 is caused by changes (mutations) in the STXBP1 gene and is inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person. For example, certain medications are often prescribed to help control seizures, although they are not always effective in all people with the condition.

MalaCards based summary : Stxbp1 Encephalopathy with Epilepsy, also known as early infantile epileptic encephalopathy 4, is related to epileptic encephalopathy, early infantile, 4 and encephalopathy, and has symptoms including tremor, absence seizures and myoclonic seizures. An important gene associated with Stxbp1 Encephalopathy with Epilepsy is STXBP1 (Syntaxin Binding Protein 1). Affiliated tissues include brain.

Genetics Home Reference : 25 STXBP1 encephalopathy with epilepsy is a condition characterized by recurrent seizures (epilepsy), abnormal brain function (encephalopathy), and intellectual disability. The signs and symptoms of this condition typically begin in infancy but can first appear later in childhood or early adulthood. In many affected individuals, seizures stop in early childhood with the other neurological problems continuing throughout life. However, some people with STXBP1 encephalopathy with epilepsy have seizures that persist.
