Gene Linked with Epileptic seizures!

Ancient gene linked to Epileptic seizures

This is an artist’s visualization of the human brain. New research points to a genetic route to understanding and treating epilepsy. Timothy Jegla, an assistant professor of biology at Penn State University, has identified an ancient gene family that plays a role in regulating the excitability of nerves within the brain. The research is scheduled to be published in the early online version of the journal Nature Neuroscience on Aug. 1, 2010.

That Sync is the cause for seizures is well-known to scientists. Read Steven Strogatz’s book Sync

In collaboration with Jeffrey Noebels at Baylor College of Medicine, the team used an electroencephalography (EEG) device to monitor the brains of mice. They found that mice missing the Kv12.2 gene did indeed have frequent seizures, albeit without convulsions. The team then stimulated mice with a chemical that induces convulsive seizures. They found that normal mice had a much higher convulsive-seizure threshold than mice with a defective Kv12.2 gene. The team also found the same results when they used a chemical inhibitor to block the Kv12.2 potassium channel in normal mice.
