*If prior authorization is not submitted, test may be delayed.
Test Overview
NOG (exonic and intronic splice site consensus) sequences are amplfied using specific primers and bidirectionally sequenced using a fluorescent method.
Confirmation of a diagnosis of Proximal Symphalangism (SYM1, OMIM # 185800) or Multiple Synostoses Syndrome 1 (SYNS1, OMIM #186500). NOG mutation analysis is also useful in the diagnosis of Tarsal-Carpal Coalition Syndrome (OMIM #186570), Stapes Ankylosis with broad thumbs and toes and without Symphalangism (OMIM #184460), and Brachydactyly Type B2 (BDB2, OMIM #611377).
Interpretive report provided.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
This assay will not detect large deletions in the NOG gene or intronic mutations outside the region sequenced in the NOG gene; in addition, mutations in the NOG gene (other than the common large deletions analyzed) or mutations in other genes associated with the disease will not be identified. Variant classification reflects the current state of scientific understanding at the time of test completion. As new scientific data becomes available, the interpretation and classification of variants identified in this assay may change. Test interpretation may be impacted by the presence of a hematologic malignancy or an allogenic bone marrow transplant.

Additional Information
Most insurance carriers require prior authorization for genetic testing. Testing will not begin until insurance prior authorization is received by the laboratory or it is confirmed that prior authorization is not required. The ordering health care provider can obtain the prior authorization or request the laboratory to submit it. To obtain BCN prior authorization call Joint Venture Hospital Laboratories (JVHL) at 800-445-4979; for all other insurances, contact the plan directly. By ordering this test the clinician acknowledges that informed consent, https://mlabs.umich.edu/sites/default/files/2023-04/file/germline-conse…, has been obtained from the patient as required by applicable state or federal laws and the ordering clinician has authorization from the patient permitting MLabs to report the test results to the ordering clinician. Test includes medical geneticist interpretation of results billed as a separate additional charge. This test is not available without interpretation.
