Familial pain syndromes from mutations of the NaV1.7 sodium channel.

Abstract excerpt

The literature currently suggests that voltage-gated sodium channels play a major role in the pathogenesis of neuropathic pain. Alterations in the expression and targeting of specific sodium channels within injured dorsal root ganglia neurons appear to predispose the neurons to abnormal firing properties, allowing for the development of neuropathic pain. Mutations of one particular sodium channel (Na(v)1.7) have...
