Dissecting the phenotypes of Dravet syndrome by gene deletion.
Neurological and psychiatric syndromes often have multiple disease traits, yet it is unknown how such multi-faceted deficits arise from single mutations. Haploinsufficiency of the voltage-gated sodium channel Nav1.1 causes Dravet syndrome, an intractable childhood-onset epilepsy with hyperactivity, cognitive deficit, autistic-like behaviours, and premature death. Deletion of Nav1.1 channels sel...

Researchers from the University of Washington in Seattle studied selective heterozygous and homozygous deletions of the voltage gated sodium channel (Nav1.1) in parvalbumin (PV) or somato-statin (SST) expressing interneurons.
متن کامل[De novo SCN1A gene deletion in therapy-resistant Dravet syndrome].
Severe myoclonic epilepsy in infancy (Dravet's syndrome) is a very rare form of epilepsy. Mutations of SCN1A gene encoding voltage-gated sodium channel alpha-1 subunit are major causes of the autosomal dominant disorder. Most cases are associated with a de novo point mutation, but some patients have copy number variations. The protein encoded by the SCN1A gene plays a role in the generation and...
متن کاملDravet syndrome
"Dravet syndrome" (DS) previously named severe myoclonic epilepsy of infancy (SMEI), or epilepsy with polymorphic seizures, is a rare disorder characterized by an early, severe, generalized, epileptic encephalopathy.DS is characterized by febrile and afebrile seizures beginning in the 1st year of life followed by different types of seizures (either focal or generalized), which are typically res...
متن کاملDravet Syndrome
Dravet syndrome (DS) is one of the refractory epileptic encephalopathies [3], one of the spectra of severe myoclonic Epilepsy of Infancy (SMEI) which occurs in otherwise healthy individuals [2]. Its incidence has been estimated to be 1 in 2000040000. It is more common in males than in females. Positive family history is encountered in one fourth of the cases. DS Usually started by clonic/tonic-...
