SCN9A variants have certainly been linked to changes in pain sensitivity (in both directions), but where have they been linked to changes in risk for opiate addiction? Even for the variant identified in this paper, the fact that it was linked to increased pain doesn't necessarily mean that it would put one at an increased risk for opiate addiction; in fact, you could easily imagine the opposite. Furthermore, in spite of the strong genetic evidence, especially for the cases for congenital pain insensitivity, it has also been hard for the industry to develop Nav1.7 inhibitors, but that could mostly be due to targeting specificity. |
