Biomarkers
Biological markers in cancer
Search for the gene, protein, or marker named in a report. Each page explains why a result must be read together with the cancer type, test method, sample, and treatment history.



25 biomarkers shown
EGFR
Changes in the EGFR gene can make lung cancer cells grow more aggressively; the result affects which targeted therapy categories are worth discussing.
Assessed through 4 related test types
ALK
ALK gene fusion is one of the most important markers to discuss in advanced non-small-cell lung cancer.
Assessed through 4 related test types
ROS1
ROS1 fusion is a rare marker that can direct discussion toward specific targeted therapy categories.
Assessed through 4 related test types
KRAS
Some specific KRAS changes in lung cancer can now be targeted, while others remain limited to standard pathways or clinical trials.
Assessed through 3 related test types
MET
MET changes can be exon 14 skipping or amplification; the two are discussed differently in treatment planning.
Assessed through 3 related test types
RET
RET fusion is rare, but when found it can open discussion of a specific targeted therapy category.
Assessed through 3 related test types
BRAF
BRAF V600E mutation can be discussed in the category of combination targeted therapy for some patients.
Assessed through 4 related test types
HER2
HER2 status is assessed on tissue testing; the result affects treatment categories in stomach cancer and some lung cancers.
Assessed through 4 related test types
NTRK
NTRK fusion is very rare, but is a marker that can be discussed across cancer types.
Assessed through 3 related test types
PD-L1
PD-L1 is a protein marker assessed with a score; the score helps interpret the relevance of immunotherapy categories.
Assessed through 2 related test types
MSI / MMR
MSI/MMR status reflects DNA repair function in the tumour and can open an immunotherapy category.
Assessed through 4 related test types
CLDN18.2
CLDN18.2 is a cell-surface protein that can be a marker for a targeted therapy category in stomach cancer.
Assessed through 2 related test types
CD19
CD19 is a marker on B cells and is the basis for several cellular therapies, including some CAR-T categories.
Assessed through 3 related test types
CD20
CD20 is a classic marker in B-cell lymphoma and is the basis for a major antibody therapy group.
Assessed through 3 related test types
CD30
CD30 is an important marker in Hodgkin lymphoma and some T-cell lymphomas.
Assessed through 2 related test types
Del(17p) / TP53
17p deletion and TP53 mutation are high-risk cytogenetic factors in multiple myeloma.
Assessed through 3 related test types
TMB (tumour mutational burden)
TMB measures how many changes are present in tumour DNA and is sometimes used as an additional consideration in immunotherapy discussion.
Assessed through 1 related test types
BCMA
BCMA is a marker on plasma cells and is the basis for several advanced therapies in multiple myeloma.
Assessed through 3 related test types
GPRC5D
GPRC5D is an alternative marker on myeloma cells used when BCMA targeting is no longer effective.
Assessed through 2 related test types
CD22
CD22 is a marker on B cells used as a target in some leukemias and B-cell lymphomas.
Assessed through 2 related test types
GPC3
GPC3 is a surface protein often found in hepatocellular carcinoma and is being studied as a therapy target.
Assessed through 2 related test types
BRCA1 / BRCA2
BRCA1 or BRCA2 changes can be inherited or limited to the tumour, and affect treatment discussion as well as family risk.
Assessed through 2 related test types
MGMT
MGMT promoter methylation status is discussed in glioma and relates to how cells repair damage caused by certain drugs.
Assessed through 2 related test types
FLT3
Changes in the FLT3 gene are findings often discussed in acute myeloid leukemia.
Assessed through 2 related test types
BCR-ABL
The BCR-ABL transcript is a defining marker in chronic myeloid leukemia and some acute lymphoblastic leukemia.
