Seizures Due to a KCNQ2 Mutation: Treatment with Vitamin B6.
London, United Kingdom. In Jimd Rep, 08 Nov 2015
Whole-exome sequencing was used to identify a de novo mutation (c.629G>A; p.Arg210His) in KCNQ2 in a 7-year-old patient whose neonatal seizures showed a response to pyridoxine and who had a high plasma to CSF pyridoxal 5'-phosphate ratio, usually indicative of an inborn error of vitamin B6 metabolism.
Genetics of pediatric epilepsy.
Durham, United States. In Pediatr Clin North Am, Jun 2015
Examples of that include the need to avoid specific drugs in Dravet syndrome and the ongoing investigations of the potential use of new directed therapies such as retigabine in KCNQ2-related epilepsies, quinidine in KCNT1-related epilepsies, and memantine in GRIN2A-related epilepsies.
Celecoxib and ion channels: a story of unexpected discoveries.
Oulu, Finland. In Eur J Pharmacol, Jun 2014
In experimental systems varying from Drosophila to primary mammalian and human cell lines, celecoxib inhibits many voltage-activated Na(+), Ca(2+), and K(+) channels, including NaV1.5, L- and T-type Ca(2+) channels, KV1.5, KV2.1, KV4.3, KV7.1, KV11.1 (hERG), while stimulating other K(+) channels-KV7.2-5
Potassium channel genes and benign familial neonatal epilepsy.
Tübingen, Germany. In Prog Brain Res, 2013
Among them, KCNQ2 and KCNQ3, coding for KV7.2 and KV7.3 voltage-gated potassium channels, present an example how genetic dissection of an epileptic disorder can lead not only to a better understanding of disease mechanisms but also broaden our knowledge about the physiological function of the affected proteins and enable novel approaches in the antiepileptic therapy design.
