VistaSeq® MSH2 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 MSH2-related Lynch syndrome.
Special Instructions
A hereditary cancer clinical questionnaire is required to accompany all specimens. Coordination with Labcorp's genetic services is advised for test ordering. Contact details and procedures for obtaining saliva collection kits are provided. Ensure that all specimens are collected in compliance with the specified guidelines.
Limitations
The test may not detect noncoding or deep intronic variants, mosaic variants, certain genomic rearrangements, or exact breakpoints of deletions/duplications. It is not intended for identifying somatic variants or for use in bone marrow transplantation context. The presence of pseudogenes like PMS2CL could interfere with variant detection in related genes. Comprehensive diagnosis may require correlation with other clinical information and tests.
