Potassium channels: Pain perception in hidradenitis suppurativa may be significantly influenced by the dysregulation of potassium channels, including genes such as KCNMA1, KCNQ5, KCNB2, KCND2, KCND3, and KCNAB3, all of which were identified in this study. The gene discussed is KCND2; the disease is hidradenitis suppurativa.
