"EA-1 is due to different heterozygous missense point mutations in a voltage gated (delayed rectifier) potassium channel gene (KCNA1 and Kv1.1) on chromosome 12p13, whereas EA-2 is caused by mutations of the cerebral P/Q-type calcium channel alpha 1 subunit gene CACNL1A4 localized on chromosome 19p, which is highly expressed in the cerebellum."
