Lynch/Colorectal High Risk Panel

Forms and Documents

Test Details

  • Colorectal or endometrial cancer diagnosed under 50 years of age
  • Multiple colon polyps (especially ≥ 20 adenomas) at any age
  • Tumor testing which indicates an increased risk for a hereditary cancer syndrome known as Lynch syndrome (e.g. microsatellite instability and/or lack of immunohistochemistry staining for a mismatch repair protein)
  • Multiple cancers in one person either of the same origin (such as two separate colorectal cancers) or of different origin (such as colon and endometrial cancer in the same individual)
  • Multiple relatives diagnosed with the same or related cancers (such as colon, endometrial, ovarian, urinary tract, gastric) on the same side of the family and spanning multiple generations
  • Deletion/Duplication Analysis
  • Next-Gen Sequencing
  • MLPA
