Telomere Biology Disorders Gene Panel, Varies
Use
This test provides a comprehensive genetic evaluation for patients with a personal or family history suggestive of a telomere biology disorder. Its purpose is to establish a diagnosis, allowing for appropriate management and surveillance for disease features based on the gene and/or variant involved. This test also aids in identifying disease-causing variants within genes associated with telomere defects, facilitating predictive testing of at-risk family members.
Special Instructions
A previous bone marrow transplant from an allogenic donor will interfere with testing. Contact Mayo Clinic Laboratories for instructions if the patient has received a bone marrow transplant.
Limitations
This test is specifically validated for detecting germline variants and may not effectively detect somatic variants associated with tumorigenesis. It does not provide diagnostic, prognostic, or therapeutic information for somatic variants. Next-generation sequencing might not detect all genomic variants due to technological constraints. False-negative or false-positive results are possible. Regions of high GC content and repetitive sequences may be less effectively evaluated. The test may not detect mosaicism or differentiate somatic from germline variants. Confirmation of results may require additional testing methodologies.
