WebbThe inherited form of erythromelalgia has recently been linked to mutations in voltage-gated sodium channel Nav1.7, which is expressed in peripheral nociceptors. Erythromelalgia and the following acral erythemas can usually be distinguished from chemotherapy-induced hand foot syndrome. Webb29 juni 2024 · Gain-of-function mutations in voltage-gated sodium channel Na V 1.7 cause severe inherited pain syndromes, including inherited erythromelalgia (IEM).
