Voltage Gated Sodium Channels Epilepsy

Voltage Gated Sodium Channels Epilepsy. A noteworthy class of ion channel genes are the voltage gated sodium channels (vgscs) that play key roles in the depolarization phase of action potentials in neurons. Abnormal vgsc activity is central to the pathophysiology of epileptic seizures, and many of the most widely used antiepileptic drugs, including phenytoin, carbamazepine, and lamotrigine, are inhibitors of vgsc function.

The basis of epilepsy is an increase in neuronal excitability that, in some cases, may be caused by functional defects in neuronal voltage gated sodium channels, nav1.1 and nav1.2.

Animal experiments, and particularly functional investigations on human chronically epileptic tissue as well as genetic studies in epilepsy patients and their families strongly suggest that some forms of epilepsy may share a pathogenetic mechanism: Epilepsy is a brain disorder characterized by seizures and convulsions.

Genetic epilepsy occurs as a result of mutations in either a single gene or an interplay of different genes. The vast majority of these mutations are in the scn1a gene, and all are dominantly inherited.

This review summarizes the neurobiology of vgscs, their association with different epilepsy syndromes, and the ways in which we can experimentally interrogate their function. Amongst the calcium channel subtypes, hva channels generally display slower activation and faster deactivation that lva channels.

That said, several genetic variations in nav channels have been described and associated with epilepsy. As epilepsy, migraine, neurodegenera tive diseases, and neuropathic pain, involve abnormalities of neuronal excitability. They are essential for normal neurologic function and are, currently, the most common recognized cause of genetic epilepsy.
