From genes to pain: Na v 1.7 and human pain disorders.

Abstract excerpt

Gain-of-function mutations or dysregulated expression of voltage-gated sodium channels can produce neuronal hyperexcitability, leading to acute or chronic pain. The sodium channel Na(v)1.7 is expressed preferentially in most slowly conducting nociceptive neurons and in sympathetic neurons. Gain-of-function mutations in the Na(v)1.7 channel lead to DRG neuron hyperexcitability associated with severe pain, whereas...
