Genomic Unity® Comprehensive 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® Comprehensive 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® Whole Genome Analysis.

Short tandem repeats:
Due to the variable nature of repetitive sequence and sequence specific differences in detection, repeat evaluation and orthogonal confirmation is performed on a case-by-case basis. Reportable pathogenic or intermediate repeat expansions may be reported with or without repeat count.
