New mutations of SCN4A cause a potassium-sensitive normokalemic periodic paralysis

14 Dec 2004

Abstract excerpt

BACKGROUND: Periodic paralysis is classified into hypokalemic (hypoPP) and hyperkalemic (hyperPP) periodic paralysis according to variations of blood potassium levels during attacks. OBJECTIVE: To describe new mutations in the muscle sodium channel gene SCN4A that cause periodic paralysis. METHODS: A thorough clinical, electrophysiologic, and molecular study was performed of four unrelated families who presented...
