SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Access to comprehensive tissue-specific gene expression data and regulatory variant information is essential for interpreting genetic associations. This Skill provides a streamlined way to query the GTEx API for median tissue expression, eQTLs, and sQTLs to map variants to gene regulation across tissues.

Core Features & Use Cases

  • Access expression data across 54 tissues via GTEx API endpoints (medianGeneExpression, geneExpression).
  • Retrieve significant eQTLs and sQTLs to link genetic variants to expression changes in tissue contexts.
  • Support GWAS interpretation by prioritizing tissues and performing cross-tissue regulatory analyses.

Quick Start

Query GTEx for a given gene to retrieve tissue-specific expression and associated eQTLs/sQTLs across tissues.

FAQPage Schema
How do I query the GTEx API for tissue-specific gene expression and eQTL data?

Query the GTEx API for tissue-specific gene expression and eQTL data by specifying gene identifiers and tissueSiteDetailId parameters. Use endpoints like medianGeneExpression and association/singleTissueEqtl with dataset versioning like gtex_v10 to retrieve expression and regulatory variant associations across 54 tissues.

Can I retrieve sQTL associations alongside eQTLs for multi-tissue regulatory variant analysis?

Yes, you can retrieve sQTL associations alongside eQTLs for multi-tissue regulatory variant analysis. The Skill queries GTEx association endpoints to link genetic variants to both expression and splicing changes across tissue contexts, supporting cross-tissue regulatory analyses.

What is the best way to interpret GWAS loci using tissue-specific expression and QTL data?

Interpreting GWAS loci using tissue-specific expression and QTL data involves querying GTEx for median tissue expression and significant eQTLs/sQTLs. This approach prioritizes relevant tissues and maps regulatory variants to gene regulation across tissues for GWAS interpretation.

Does this approach support dataset versioning for GTEx API queries?

Yes, this approach supports dataset versioning for GTEx API queries. It requires specifying dataset versions like gtex_v10 to ensure accurate retrieval of expression and regulatory variant association data across tissue contexts.

How do I handle pagination when retrieving significant eQTLs from the GTEx API?

Handle pagination when retrieving significant eQTLs from the GTEx API by implementing proper pagination handling in your queries. This ensures complete retrieval of association data from endpoints like association/singleTissueEqtl across all relevant tissues.

When do I need to specify tissueSiteDetailId parameters for GTEx tissue expression queries?

Specify tissueSiteDetailId parameters for GTEx tissue expression queries when targeting specific tissues across the 54 available options. These parameters are required by endpoints like medianGeneExpression to retrieve tissue-specific gene expression data accurately.
