The Nav1.7 sodium ion channel protein is encoded by gene SCN9A.
Recent studies have associated a defect in SCN9A with congenital insensitivity to pain.
|Membrane transport protein: ion channels
||Voltage-dependent calcium channel (L-type/CACNA1C, N-type, P-type, Q-type, R-type, T-type) - Inositol triphosphate receptor - Ryanodine receptor - Cation channels of sperm
