David Beeson info - CACNA1A. antibodies to gene protein cause lambert-Eaton myasthenic syndrome. Usually mutations in this gene cause episodic ataxia, or hemiplegic migraine or spinal cerebella ataxia, but have recently come across case where EMG evidence of decrement and fatiguable muscle weakness consistent with a myasthenic syndrome. Dominant. Within family pedigree. No other example for episodic ataxia plus myasthenic syndrome although one previous report of hemiplegic migraine plus disturbed NMJ function. Majority of mutations lead to episodic ataxia/hemiplegic migraine.Created: 29 Apr 2019, 4:33 p.m.
