SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Facilitates access to GTEx data to interpret how genetic variation influences gene expression across tissues, aiding the assignment of regulatory mechanisms to GWAS signals.

Core Features & Use Cases

  • GTEx REST API v2 access to expression and QTL data across 54 tissues
  • Retrieve median gene expression by tissue and identify tissue-specific patterns
  • Query eQTL and sQTL associations to connect variants with regulatory effects in relevant tissues
  • Use cases: prioritize tissues for disease associations, perform colocalization analyses, and validate regulatory hypotheses with tissue-specific data

Quick Start

Identify a gene of interest and query its tissue-specific expression and eQTLs across GTEx tissues.

FAQPage Schema
How do I retrieve tissue-specific gene expression data from GTEx?

To retrieve tissue-specific gene expression from GTEx, query the API v2 endpoints using a GENCODE ID to get median expression levels across 54 tissues in v8 or v10 datasets.

How can I find eQTLs and sQTLs for a specific genetic variant?

Find eQTLs and sQTLs for a specific variant by querying GTEx API v2 endpoints, which return association data including p-values and q-values to link variants with regulatory effects across tissues.

What is the best way to connect GWAS signals to regulatory mechanisms?

Connect GWAS signals to regulatory mechanisms by querying GTEx eQTL and sQTL data to identify tissues where your variants affect gene expression, validating regulatory hypotheses with tissue-specific data.

What do I need to query GTEx data for gene expression analysis?

Querying GTEx data requires a target gene or variant, corresponding GENCODE IDs, and proper handling of API v2 pagination to successfully retrieve expression and QTL associations.

Why use GTEx v10 over v8 datasets for tissue-specific gene expression?

Use GTEx v10 over v8 to access updated tissue-specific gene expression and QTL annotations, allowing comparative analysis across different dataset versions to validate regulatory findings.
