Genomic Unity® Ataxia 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.
With its single method approach to detecting and analyzing tandem repeat expansions, structural variants and small sequence changes, Genomic Unity® Ataxia Analysis is an effective test for diagnosis of ataxias. It provides comprehensive coverage of ataxia-related genes in addition to the ataxia repeat expansion loci that are the focus of Genomic Unity® Ataxia Repeat Expansion Analysis.
Order this test when the patient presents with symptoms of ataxia and you'd like the option to test a broader set of genes than just the 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.
