Tyrosine Disorders Gene Panel, Varies
Use
This test is used for the follow-up of abnormal biochemical results suggestive of a tyrosine disorder. It establishes a molecular diagnosis for patients with tyrosine disorders by identifying variants within genes known to be associated with these disorders. This allows for a more targeted diagnosis and treatment plan, helps with genetic counseling, and enables predictive testing for at-risk family members. The identification of a disease-causing variant can aid diagnosis, prognosis, clinical management, and familial screening.

Limitations
Next-generation sequencing may not detect all variants in FAH, HGD, HPD, and TAT genes. False negatives can occur, and confirmation with additional methods may be needed. The ability to detect variants may be affected by factors such as DNA quality, quantity, and sequence variants in primer binding sites that could affect PCR. Copy number variants can also be challenging to detect and interpret accurately without further testing.
