Genomic Unity Exome Analysis (includes STR analysis of 26 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.: GTR000591934.3

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 Hereditary disease

E.g., 'Bi-directional sequencing of exons 1-5 with concurrent analysis of Glu234Gly'.This test includes repeat expansion analysis of 27 loci: AFF2, AR, ATN1, ATXN1, ATXN2, ATXN3, ATXN7, ATXN8OS, ATXN10, C9ORF72, CACNA1A, CNBP, CSTB, DIP2B, DMPK, FMR1, FXN, HTT, JPH3, NOP56, NOTCH2NLC, PABPN1, PHOX2B, PPP2R2B, TBP, TCF4.
Test development
HelpHow the test was developed (e.g. Laboratory Developed Test (LDT), FDA reviewed, externally manufactured kit, modified FDA-reviewed test, or combination). Intended to help differentiate certification requirements between the test types. Reflex testing not included here.Not provided
Test procedure
HelpSummary of the test methodology and/ or description of the specific steps for each method used in this assay.The patient's DNA is sequenced using whole genome sequencing conducted on an Illumina platform using the Illumina TruSeq DNA PCR-Free Library Preparation Kit at 30X mean mappable coverage. The relevant region(s) of DNA are subsequently isolated in-silico for analysis.
