Cholestasis Sponsored Testing Program
Use
This sponsored testing program aims to identify genetic causes of cholestasis in patients who meet specific clinical criteria. By sequencing 143 genes associated with cholestasis and related disorders, it helps in diagnosing unexplained chronic liver diseases, offering insights into appropriate management and treatment strategies. Patients who have idiopathic cholestasis or family history indicating genetic predisposition can benefit from this diagnostic tool. It supports the identification of underlying genetic conditions, enabling personalized patient care.
Special Instructions
Not provided.
Limitations
The test is restricted to the listed 143 genes and may not cover other potential genetic causes of cholestasis. DNA from buccal swabs may be contaminated, which could impact test quality and require additional specimens. This test has not been cleared or approved by the FDA, which may limit its clinical application in certain scenarios. Results should be interpreted in the context of complete clinical evaluation and family history. Potential for changes in gene panel composition over time as new genetic knowledge evolves.
