Genomic UnityⓇ Ataxia Repeat Expansion Analysis (STR analysis of 16 loci)
- GTR Test IDHelpEach Test is a specific, orderable test from a particular laboratory, and is assigned a unique GTR accession number. The format is GTR00000001.1, with a leading prefix 'GTR' followed by 8 digits, a period, then 1 or more digits representing the version. When a laboratory updates a registered test, a new version number is assigned.: GTR000576331.8

- Test version history
Clinical testHelpIn the U.S., clinical tests must be performed under CLIA certification. When a lab uses the same methods for a test in both clinical and research settings, the test appears as two separate GTR records. for Spinocerebellar ataxia type 1

Testing strategy
HelpThe lab's suggested sequence of ordering tests based on clinical scenarios. It may include information on: reflex testing including each test component, and scenarios which prompt additional components of testing; whether lab communicates interim results or automatically proceeds to further analyses; and if any components are performed in another laboratory.When results are not positive, there is an option to reflex up to Genomic UnityⓇ Exome Analysis or Genomic UnityⓇ Exome Plus Analysis, and Genomic UnityⓇ Whole Genome Analysis. 000 Genomic Unity Ataxia Repeat Expansion Analysis orders are initiated at https://www.variantyx.com/resources/provider-resources/order-forms/.
