Dravet syndrome: a new causative SCN1A mutation?
نویسندگان
چکیده
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.

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...

BACKGROUND Dravet syndrome, a rare genetic disorder with early-onset epileptic encephalopathy, was first described by Dravet in 1978. Dravet syndrome is most frequently caused by various mutations of the SCN1A gene encoding the type 1 subunit of the neuronal voltage-gated sodium channel. CASE PRESENTATION Two sisters of a non-consanguineous Palestinian family from the Arab community in Israel...

OBJECTIVE The aim of this study was to characterize the SCN1A mutation spectrum in Korean patients with Dravet syndrome. METHODS Twenty-nine patients diagnosed with Dravet syndrome at the Seoul National University Children's Hospital were included in the study. Direct sequencing and multiplex ligation-dependent probe amplification (MLPA) were used to identify SCN1A mutations. Mutations were c...
متن کاملMosaicism of a missense SCN1A mutation and Dravet syndrome in a Roma/Gypsy family.
SCN1A mutations account for a large proportion of Dravet syndrome patients, and are reported in other cases of epilepsy, such as some families with genetic epilepsy with febrile seizures plus (GEFS+). While most Dravet syndrome cases are caused by de novo mutations, 5% inherit a mutation from a mildly affected or symptom-free parent. Parental mosaicism has been identified, with documented cases...
متن کاملUpregulation of Haploinsufficient Gene Expression in the Brain by Targeting a Long Non-coding RNA Improves Seizure Phenotype in a Model of Dravet Syndrome
Dravet syndrome is a devastating genetic brain disorder caused by heterozygous loss-of-function mutation in the voltage-gated sodium channel gene SCN1A. There are currently no treatments, but the upregulation of SCN1A healthy allele represents an appealing therapeutic strategy. In this study we identified a novel, evolutionary conserved mechanism controlling the expression of SCN1A that is medi...
