description	Biomarker Discovery Pipeline - Discover biomarkers: TCGA differential expression, NCBI gene data, OpenTargets associations, and clinical relevance. Use this skill for precision medicine tasks involving tcga differential expression analysis get gene metadata by gene name get associated targets by disease efoId clinvar search. Combines 4 tools from 4 SCP server(s).

Biomarker Discovery Pipeline

Discipline: Precision Medicine | Tools Used: 4 | Servers: 4

Description

Discover biomarkers: TCGA differential expression, NCBI gene data, OpenTargets associations, and clinical relevance.

Tools Used

• tcga_differential_expression_analysis from tcga-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/11/Origene-TCGA
• get_gene_metadata_by_gene_name from ncbi-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/9/Origene-NCBI
• get_associated_targets_by_disease_efoId from opentargets-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/15/Origene-OpenTargets
• clinvar_search from search-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/7/Origene-Search

Workflow

1. Run TCGA differential expression
2. Get gene metadata
3. Get OpenTargets associations
4. Search ClinVar variants

Test Case

Input

{
    "query": "biomarkers for breast cancer",
    "gene": "BRCA1",
    "disease_efo": "EFO_0000305"
}

Expected Steps

1. Run TCGA differential expression
2. Get gene metadata
3. Get OpenTargets associations
4. Search ClinVar variants

Usage Example

Note: Replace sk-b04409a1-b32b-4511-9aeb-22980abdc05c with your own SCP Hub API Key. You can obtain one from the SCP Platform.
