Biological Classification

The Biological Classification section of the Biomarker Details page summarizes all biological assertions previously created for the variant across all sources (i.e., My Knowledge Base, OncoKB, CKB).

If you have existing knowledge to upload to the system, refer to Upload Assertions.

You can filter assertions by source, diseases, and summary. Filter changes are saved and applied across variants within a case and can be reset if needed.

Assertion Details

Field Name	Description
Directional Arrows	Opens to view the assertion summary and update date.
Biomarker	Indicates how the assertion is related to the variant (for example, specific amino acid change or specific exon change).
HRD	Indicates whether an assertion is associated with HRD positive or negative. This column is available for GIS and variants when the selected transcript is for BRCA1/2.
Classification	This column displays the classification as indicated by the knowledge base.
Type	The assertion type (for example, biological). For more information, refer to Interpret a Variant.
Disease	The disease associated with the classification.
Previously Reported Icon	Any cases where the assertion was previously reported.
Actions	This column contains the following available actions: • Add to report • Archive, if the assertion is in My Knowledge Base • Copy to New Assertion, if the assertion is not in My Knowledge Base To edit an assertion, add it to the report before editing. For more information, refer to Manage Assertions.
