CACNA1A


Also found in: Acronyms.

CACNA1A

A gene on chromosome 19p13 that encodes the alpha-1A subunit of a voltage-dependent P/Q-type calcium channel, which mediates the entry of calcium ions into excitable cells. These channels are also involved in various calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and apoptosis.

Molecular pathology
CACNA1A mutations are associated with familial hemiplegic migraine and episodic ataxia 2.
