VistaSeq® PMS2 Comprehensive Analysis
Also known as: Familial Cancer testing, Hereditary Cancer testing, Inherited Cancer testing
Use
This assay is intended for patients with a personal or family history consistent with PMS2-related Lynch syndrome.
Special Instructions
A hereditary cancer clinical questionnaire should be submitted with all specimens. Contact CMBP genetic services at 800-345-4363 to coordinate testing. To order Oragene Dx 500 saliva collection kits using PeopleSoft No. 87917, contact your local Labcorp branch supply department.
Limitations
Sequencing cannot detect variants in regions not covered by this analysis, including noncoding or deep intronic variants and may not reliably detect changes in repetitive elements, such as microsatellite repeats. It may not detect mosaic variants, inversions, or genomic rearrangements. The presence of pseudogenes like PMS2CL can interfere with detecting variants, complicating deletion/duplication analysis. Some genomic rearrangements, including certain translocations and partial exon rearrangements, may not be identified. The test does not determine exact breakpoints and is not intended for detecting somatic variants. Bone marrow transplantation may affect outcomes.
