Part Description
LP19785-2 CACNA1A gene
The CACNA1A gene (calcium channel, voltage-dependent, P/Q type, alpha 1A subunit) [HGNC Gene ID:1388] is located on chromosome 19p13. Voltage-dependent calcium channels mediate the entry of calcium ions into excitable cells, and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, and gene expression. Calcium channels are multisubunit complexes composed of alpha-1, beta, alpha-2/delta, and gamma subunits. The channel activity is directed by the pore-forming alpha-1 subunit, whereas, the others act as auxiliary subunits regulating this activity. The distinctive properties of the calcium channel types are related primarily to the expression of a variety of alpha-1 isoforms, alpha-1A, B, C, D, E, and S. This gene encodes the alpha-1A subunit, which is predominantly expressed in neuronal tissue. Mutations in this gene are associated with 2 neurologic disorders, familial hemiplegic migraine and episodic ataxia 2. This gene also exhibits polymorphic variation due to (CAG)n-repeats. Multiple transcript variants encoding different isoforms have been found for this gene. In one set of transcript variants, the (CAG)n-repeats occur in the 3' UTR, and are not associated with any disease. But in another set of variants, an insertion extends the coding region to include the (CAG)n-repeats which encode a polyglutamine tract. Expansion of the (CAG)n-repeats from the normal 4-16 to 21-28 in the coding region is associated with spinocerebellar ataxia 6. [provided by RefSeq, Mar 2010] [NCBI Gene ID:773]

- Change Reason
- Based on LOINC Committee review (June 2016), "targeted" was added to the Component to clarify that this test is looking for a specific set of mutations as described in the LOINC User Guide under the Molecular Genetics section.; Based on LOINC Committee review (June 2019), updated the Property from "Prid" to "Find" and Scale from "Nar" to "Doc" to align with the current LOINC model for naming collections of information reported in narrative and/or structured formats.
