Other potassium channel genes that are proposed to be involved in experimental neuropathic pain are Kcnip3, Kcnj6, Kcnq2 and Kcnq3.45 Besides differential expression of these genes in rats after CCI-ION, the specific role of these potassium channel genes in experimental trigeminal neuropathic pain is not further discussed by the authors. This evidence concerns the gene KCNQ3 and Pain.
