OncoAlly™ Hereditary Colorectal Cancer Analysis

Test Code – OA013

OncoAlly™ Colorectal Cancer Analysis uses a whole genome sequencing platform to analyze 21 genes for genetic variants associated with hereditary colon cancer..

When to Order

Order this test when a patient has a personal or family history suggestive of hereditary colorectal cancer predisposition or when germline variant analysis for hereditary colorectal cancer predisposition is necessary to guide medical management.

Included Analyses

  • Sequence analysis of hereditary cancer-associated genes (single nucleotide variants, deletions, insertions, and characterized intronic variants)
  • Copy number variant analysis of hereditary cancer-associated genes (duplications/deletions, mobile element insertions, and inversions)

Optionally Includes:

Included Genes

Note: The PMS2 gene contains regions that are non-unique, therefore not all variants can be assigned to the correct location, limiting interpretation.
