Identification of SCN1A and PCDH19 Mutations in Chinese Children with Dravet Syndrome
BACKGROUND Dravet syndrome is a severe form of epilepsy. Majority of patients have a mutation in SCN1A gene, which encodes a voltage-gated sodium channel. A recent study has demonstrated that 16% of SCN1A-negative patients have a mutation in PCDH19, the gene encoding protocadherin-19. Mutations in other genes account for only a very small proportion of families. TSPYL4 is a novel candidate gene...
متن کاملDravet syndrome: a new causative SCN1A mutation?
Dravet syndrome is often caused by SCN1A mutations and has a wide variation in clinical appearance. Indication for genetic analysis should be an epileptic encephalopathy or severe clinical course of seizures in infants with episodes of fever before the first year of life.
متن کاملGenetic diagnosis of severe myoclonic epilepsy of infancy (Dravet syndrome) with SCN1A mutations in the Hong Kong Chinese patients.
Epilepsy is a clinically and genetically heterogeneous group of disorders. The advent of molecular genetics brings unprecedented advancement in diagnostic molecular pathology and reduces over-reliance on traditional clinical classification. Severe myoclonic epilepsy of infancy or Dravet syndrome is a catastrophic infantile-onset epilepsy. We report two unrelated Hong Kong Chinese patients with ...
متن کاملClinical and genetic factors predicting Dravet syndrome in infants with SCN1A mutations.
OBJECTIVE To explore the prognostic value of initial clinical and mutational findings in infants with SCN1A mutations. METHODS Combining sex, age/fever at first seizure, family history of epilepsy, EEG, and mutation type, we analyzed the accuracy of significant associations in predicting Dravet syndrome vs milder outcomes in 182 mutation carriers ascertained after seizure onset. To assess the...
متن کاملEfficacy of Stiripentol in Dravet Syndrome with or without SCN1A Mutations
BACKGROUND AND PURPOSE The aim of this study was to determine the effectiveness of stiripentol (STP) add-on therapy to valproate and clobazam in patients with Dravet syndrome (DS) according to the presence of mutations in the sodium channel alpha-1 subunit gene (SCN1A). METHODS We performed direct sequencing to analyze SCN1A mutations in 32 patients with clinically confirmed with DS, and clas...
