SNP Functional Impact Analysis

Discipline: Functional Genomics | Tools Used: 4 | Servers: 2

Description

Analyze SNP function: VEP prediction, variation details, phenotype association, and literature evidence.

Tools Used

• get_vep_id from ensembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/12/Origene-Ensembl
• get_variation from ensembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/12/Origene-Ensembl
• get_phenotype_accession from ensembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/12/Origene-Ensembl
• pubmed_search from search-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/7/Origene-Search

Workflow

1. Predict functional effects with VEP
2. Get variant details
3. Get phenotype associations
4. Search PubMed for evidence

Test Case

Input

{
    "variant_id": "rs1800497",
    "species": "homo_sapiens"
}

Expected Steps

1. Predict functional effects with VEP
2. Get variant details
3. Get phenotype associations
4. Search PubMed for evidence

Usage Example

Note: Replace <YOUR_SCP_HUB_API_KEY> with your own SCP Hub API Key. You can obtain one from the SCP Platform.
