BiomarkerKB collects data from many different resources. The data that is collected is not always directly integrated into the data model and data from a resource is sometimes just added as valuable contextual annotations or cross references.

Other resources to be explored: CADSR Cancer, https://themarker.idrblab.cn/, biomarker.org, ResMarkerDB, SalivaDB, https://glycanage.com/publications, https://www.c, Glycan Biomarkers (code)


Please contact us at mazumder_lab@gwu.edu and daniallmasood@gwu.edu if you have any other resources that may contain biomarker data

CIViC

Status: Direct Integration into Data Model

  • Clinical Interpretation of Variants in Cancer (CIViC).
  • Provides cancer biomarkers in form of DNA mutations (dbSNPs).
  • Platform provides clinicians treatment options for patients based on unique tumor profile.
  • License: Creative Commons Attribution-NonCommercial 4.0 International License.

ClinVar

Status: Direct Integration into Data Model

  • Public archive of reports of human variations classified for diseases and drug responses.
  • Provides biomarkers for all disease, but we have only curated cancer biomarkers for now.
    • dbSNPs
    • File is really big but will go back and use existing script to map all biomarkers from here into the data model.
  • License: Creative Commons Attribution-NonCommercial 4.0 International License.

EDRN

Status: Sample Integration into Data Model

  • Cancer biomarkers.

GWAS

Status: Direct Integration into Data Model

  • Published genome-wide association studies (GWAS).
  • Provides biomarkers in form of SNPs.
  • GWAS Catalog contains SNPs for a vast amount of diseases.
    • Preliminary curation only focused on cancer.
    • Will use existing script to map all biomarkers into data model.
  • License: Creative Commons Attribution-NonCommercial 4.0 International License.

HPO

Status: Cross-Reference

  • HPO provides disease and entity associations.
  • Does not provide a change within the entity so we cannot collect biomarker data from here.
  • However we can use it as a cross-reference within our cross-referencing section.
  • Provides cross-reference to OMIM, SNOMED, and MONDO.

LOINC

Status: Cross-Reference

Data provided by Metabolomics Workbench

MarkerDB

Status: Direct Integration into Data Model

  • Provides a lot of useful biomarker data and cross-references other resources as well.
  • Information includes: panel information, abnormal levels of biomarkers by disease, structural information, etc.
  • Annotations that can be cross-referenced include the above.
  • By cross-referencing, BiomarkerKB will allow users to find more information for specific biomarkers and move towards the goal of being a comprehensive resource for biomarkers.
  • License: Creative Commons Attribution-NonCommercial 4.0 International License.

Metabolomics Workbench

Status: Direct Integration into Data Model

Data provided by Metabolomics Workbench

  • Metabolite biomarkers utilized in the uniform newborn screening program.
  • Detect treatable disorders that are life threatening or having long-term morbidity, before they become symptomatic.

OncoKB

Status: Cross-Reference

  • Provides useful information on drugs and therapy options for different biomarker entities.
  • Also provides information based on what condition the entity is related to.
  • License: A license is required to use OncoKB for commercial and/or clinical purposes, and to access OncoKB data programmatically for academic purposes.
  • Paid license is required
  • Cross-reference from biomarkers in BiomarkerKB to the appropriate drug information and therapy information is the best solution.

OncoMX

Status: Direct Integration into Data Model

  • integrated cancer mutation and expression resource for exploring cancer biomarkers
  • Manual curation effort by GWU and JPL
  • Over 600 single and panel biomarkers
  • License: Creative Commons Attribution-NonCommercial 4.0 International License.

OpenTargets

Status: Direct Integration into Data Model

  • Collects potential drug targets and therapeutic targets.
  • Some effort was required to find the correct biomarker data.
  • 1200 biomarkers collected.
    • dbSNPs related to cancer and other disease
  • License: Creative Commons Attribution-NonCommercial 4.0 International License.

PubMed Central Biomarker Gene Set Curation

Status: Direct Integration into Data Model

Data provided by Avi Ma'ayan's LINCS group

  • This data set was created through manual curation of biomarker gene sets on Pubmed Central using the results of gene sets returned from Rummagene.
  • Using the outputted search results within the Rummagene web server, we manually identified publications that associated different conditions and environmental exposures to biomarker gene sets.
  • The biomarker gene sets were retrieved through the validation of the gene mentioned within each of the publications.
  • The primary use case for this data is to identify biomarker panels/ gene sets associated with conditions.

UniProtKB

Status: Direct Integration into Data Model

  • Can provide biomarker (change in entity), entity, condition, and sampling data.
  • This data is in a text file that has to be reviewed fully and to make sure it will be able to be automatically extracted.
  • Contextual information can be imputed if necessary.
  • In UniProt there are found_in and entries that are actual biomarkers:
    • found_in will get a cross-reference;
    • actual biomarkers will be directly integrated.
  • Manual curation of 56 reviewed entries with mention of "biomarker" in flat text file.
  • License is Creative Commons Attribution 4.0 International (CC BY 4.0).

MetaKB

Status: Direct Integration into Data Model

  • Provides harmonized associations between cancer genomic variants, diseases, and therapeutic evidence.
  • Aggregates and standardizes variant interpretation data from six major knowledgebases:
    • CIViC (Clinical Interpretation of Variants in Cancer) [Already Integrated Directly]
    • OncoKB [Yet to be integrated]
    • JAX-CKB (The Jackson Laboratory Clinical Knowledgebase) [Yet to be integrated]
    • MolecularMatch [Yet to be integrated]
    • PMKB (Precision Medicine Knowledgebase) [Yet to be integrated]
    • Cancer Genome Interpreter (CGI) – through its Cancer Biomarkers Database component .[Integrated]
  • Enables mapping of variant–disease–drug relationships with supporting evidence levels, citations, and ontology alignment (e.g., genes, variants, diseases, and drugs).
  • Data integration requires review to ensure harmonized entity mappings consistent with the BiomarkerKB data model.
  • Focused on somatic variant–based biomarkers; contextual attributes such as tissue type, therapy response, or evidence type can be inferred or imputed where not directly specified.
  • Manual curation may be required for entries with incomplete evidence annotation or lacking standard ontology references.
  • Integration approach: direct mapping of variant, condition, and evidence entities; cross-references retained to original data sources.
  • License: Aggregated data are available for non-commercial, research use only, respecting constituent licenses:
    • CIViC – CC0 (Public Domain)
    • PMKB – CC-BY 4.0
    • CGI – CC0 for biomarkers database, CC-BY-NC 4.0 for tool
    • JAX-CKB – CC-BY-NC-SA 4.0
    • OncoKB – custom non-commercial license
    • MolecularMatch – restricted commercial use
    • MetaKB codebase – MIT license
  • Overall usage requires adherence to non-commercial research terms; commercial use needs separate permissions from individual data providers.
