Gene: [12p13/KCNA1] potassium voltage-gated channel, shaker-related subfamily, member 1; ataxia, episodic with myokymia (AEM; MIM:160120); paroxysmal ataxia with neuromyotonia, hereditary (MIM:160120); [AEMK EA1 EAM ]
HET | Kramer-1994 suggested that there are 2 autosomal dominant forms of episodic ataxia. In EA1, attacks last minutes and interictal myokymia may be present. The second form, EA-2, is often associated with nystagmus or trunkal instability and shows beneficial response to acetazolamide. The nystagmus-associated form was mapped to Chr 19p13.1 (GEM:19p131/CACNA1A)." |
