Genomic Unity® Ataxia Repeat Expansion Analysis
Ataxias are a group of neurological conditions most often related to degeneration of the cerebellum, the area of the brain responsible for coordinating movement.
Genomic Unity® Ataxia Repeat Expansion Analysis is an effective test for diagnosis of ataxias caused by tandem repeat expansion of 12 different loci. For comprehensive coverage of ataxia-related genes in addition to these repeat expansion loci, consider Genomic Unity® Ataxia Analysis.
Order this test when the patient presents with symptoms of ataxia and you'd like the option to specifically test the 12 repeat expansion loci, keeping the option reflex up to Genomic Unity® Exome Plus Analysis.

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.
