Approximately 85% of Dravet syndrome cases are caused by spontaneous, heterozygous loss of function mutations in the SCN1A
STK-001 is designed to selectively upregulate one allele of the SCN1A
gene to restore the protein expression to near-normal levels.
Bu yatkinlik genetik bir nedeni dusundurmekte olup 2001 yilinda voltaj kapili sodyum kanallarinin al alt unitesini kodlayan SCN1A
geni mutasyonlari ile hastaligin iliskisi kanitlanmistir (5).
Generalized epilepsy with febrile seizures plus(GEFS+): clinical spectrum in seven Italian families unrelated to SCN1A
, SCN1B and GABRG2 gene mutations.
Protective effect of the ketogenic diet in Scn1a
Dravet syndrome is a type of epileptic encephalopathy that is associated with SCN1A
sodium channel mutations.
Quest Diagnostics ease, ci mother sued the lab after it conducted her son's genetic testing for Dravet's disease under the theory that its failure to label her son's SCN1A
mutation as disease-causing led to his death.

 showed an increasing risk of SJS/TEN that is dependent on the epoxide hydrolase 1 (EPHX1) polymorphism, yet no influence of CYP3A4, multidrug resistance protein 1, FAS, and SCN1a
polymorphism in Chinese Han population could be observed.
Preliminary studies indicate that agnogenic EOEE might be related to gene mutation, and the results of genetic tests of part of our enrolled cases showed gene mutation in gene STXBP1, SCN1A
, and KCNQ2 in our patient, which also have been reported in the previous studies., 33 (53.2%) infants in the nEOEE group had certain etiology, and most of them were mild to moderate HIE, IVH of degree II, benign familial neonatal convulsion, transient hypoglycemia, hypocalcemia, and hypomagnesemia.
It was previously known as Severe Myoclonic Epilepsy of Infancy, and affects one out of 15,700 individuals, 80 percent of whom have a mutation in their SCN1A
gene, according to (https://www.dravetfoundation.org/what-is-dravet-syndrome/) Dravet Syndrome Foundation .
Currently, we recognize three types of FHM, each of them linked to a different gene : CACNA1A, ATP1A2, and SCN1A
. The only prevalence study was conducted in Denmark and it showed a prevalence of 0.003%, but in Portugal there are many families identified either with HM (namely type I) or with episodic ataxia type 2 or spinocerebellar ataxia type 6 [28-31].
