Genomic Unity® CACNA1A Gene Analysis

Genomic Unity® CACNA1A Gene Analysis is an effective test for certain ataxias, early infantile epileptic encephalopathy and familial hemiplegic migraine. 

For comprehensive coverage of ataxia-related genes in addition to CACNA1A, consider Genomic Unity® Comprehensive Ataxia Analysis.

Order this test when the patient presents with symptoms of certain ataxias, early infantile encephalopathy and/or familial hemiplegic migraine and you'd like the option to specifically test the CACNA1A gene, keeping the option to reflex up to Genomic Unity® Whole Genome Analysis.

  • Sequencing analysis of the CACNA1A gene
  • Del/dup analysis of the CACNA1A gene
  • Tandem repeat expansion analysis of the CACNA1A gene

Optionally includes:

  • Reflex to Genomic Unity® Whole Genome Analysis or Genomic Unity® Exome Analysis


SNVs and Indels up to 50bp
99.7% sensitivity
99.6% positive predictive value

Structural variants:
96% clinical sensitivity

Short tandem repeats:
Full mutation tandem repeats, and in some cases intermediate and/or premutation repeats, are reported with the number of repeats. All reported tandem repeat expansions are confirmed by an orthogonal technology.
