Test ID LYNCP Lynch Syndrome Panel, Varies


Ordering Guidance


This gene panel tests for germline variants in the Lynch syndrome genes. This is not a tumor test or immunohistochemistry (IHC). For information on tumor testing or IHC staining for Lynch syndrome, see TMSI / Microsatellite Instability, Tumor or IHC / Mismatch Repair (MMR) Protein Immunohistochemistry Only

 

For a comprehensive hereditary cancer panel that includes MLH1, MSH2, MSH6, PMS2, and EPCAM genes, consider ordering 1 of the following tests:

-CRCGP / Hereditary Gastrointestinal Cancer Panel, Varies

-PANCP / Hereditary Pancreatic Cancer Panel, Varies

-PRS8P / Hereditary Prostate Cancer Panel, Varies

-BRGYP / Hereditary Breast/Gynecologic Cancer Panel, Varies

 

Additional first-tier testing may be considered/recommended. For more information see Lynch Syndrome Testing Algorithm.

 

Customization of this panel or single gene analysis for any gene present on this panel is available. For more information see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.

 

Targeted testing for familial variants (also called site-specific or known mutations testing) is available for the genes on this panel. For more information see FMTT / Familial Mutation, Targeted Testing, Varies.

Useful For

Establishing a diagnosis of Lynch syndrome or constitutional mismatch repair deficiency allowing for targeted cancer surveillance based on associated risks

 

Identification of MLH1, MSH2, MSH6, PMS2, or EPCAM variants to allow for predictive testing in family members

Genetics Test Information

This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in 5 genes associated with Lynch syndrome: MLH1, MSH2, MSH6, PMS2, EPCAM (copy number variant only). For additional details see Method Description, Targeted Genes and Methodology Details for Lynch Syndrome Panel.

 

Identification of a pathogenic variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for Lynch syndrome.

 

Prior Authorization is available for this assay.
