Thrombocytopenia Absent Radius (TAR) Syndrome via the RBM8A Gene
- 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.: GTR000553109.5

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 Radial aplasia-thrombocytopenia syndrome

Methodology
Methodology
HelpThe assay's major method category (biochemical, cytogenetic or molecular genetics); method category (i.e. enzyme assay, chromosome breakage studies, targeted mutation analysis); methodology (i.e. the name of the method used) and instruments used when performing this test.- Molecular Genetics

- TTargeted variant analysis
- Bi-directional Sanger Sequence Analysis
- Applied Biosystems 3730 capillary sequencing instrument
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.Test developed by laboratory (no manufacturer test name)
Test procedure
HelpSummary of the test methodology and/ or description of the specific steps for each method used in this assay.As required, DNA is extracted from the patient specimen. PCR is used to amplify the indicated exons plus additional flanking non-coding sequence. After cleaning of the PCR products, cycle sequencing is carried out using the ABI Big Dye Terminator v.3.0 kit. Products are resolved by electrophoresis on an ABI 3730xl capillary sequencer. In most cases, sequencing is performed in both forward and reverse directions; in some cases, sequencing is performed twice in either the forward or reverse directions. In nearly all cases, the full coding region of each exon as well as 10 bases of non-coding DNA flanking the exon are sequenced.
