Electrophysiological characterization of a CaV3.1 calcium channel mutation linked to trigeminal neuralgia.

Abstract excerpt

Trigeminal neuralgia is a rare and debilitating disorder that affects one or more branches of the trigeminal nerve, leading to severe pain attacks and a poor quality of life. It has been reported that the CaV3.1 T-type calcium channel may play an important role in trigeminal pain and a recent study identified a new missense mutation in the CACNA1G gene that encodes the pore forming α1 subunit of the CaV3.1...
