SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires requests, pandas, and includes references (resource) components.

What problem does it solve?

This Skill helps researchers interpret genetic variants by querying the Genotype-Tissue Expression (GTEx) database to understand gene expression patterns and regulatory effects across different human tissues.

Core Features & Use Cases

  • Gene Expression Analysis: Retrieve median gene expression levels (TPM) across 54 human tissues.
  • eQTL and sQTL Lookup: Identify genetic variants associated with gene expression (eQTLs) or splicing (sQTLs) in specific tissues.
  • GWAS Variant Interpretation: Link non-coding GWAS variants to potential target genes by finding eQTLs in relevant tissues.
  • Use Case: Investigate how a specific genetic variant might affect the expression of a gene in the brain versus the liver.

Quick Start

Query GTEx for the median expression of the gene APOE across all tissues.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I retrieve tissue-specific gene expression data for a specific gene like APOE?

To retrieve tissue-specific gene expression data, you query the GTEx REST API v2 to get median expression levels measured in TPM across 54 human tissues. This allows you to compare expression patterns for genes like APOE across different tissue types.

How can I find eQTLs and sQTLs associated with a specific genetic variant or gene?

You can identify eQTLs and sQTLs by querying the GTEx REST API v2 for specific genetic variants or genes. This retrieves associations linking variants to gene expression or splicing variations within specific human tissues.

How do I interpret non-coding GWAS variants using tissue-specific gene regulation data?

Interpret non-coding GWAS variants by querying the GTEx database to find overlapping eQTLs in relevant tissues. This links the variant to potential target genes and reveals tissue-specific genetic associations with gene expression.

Can I retrieve a list of all eGenes for a specific human tissue using GTEx?

Yes, you can retrieve a list of eGenes per tissue by querying the GTEx REST API v2. This provides a comprehensive list of genes showing significant expression quantitative trait loci within your specified tissue.

What data sources and libraries are needed to query GTEx for tissue-specific eQTL analysis?

Querying GTEx for tissue-specific eQTL analysis requires the requests library to interact with the GTEx REST API v2 and pandas to structure the retrieved expression and genetic association data for analysis.

Does the GTEx API support comparing gene expression levels between different tissues like brain and liver?

Yes, the GTEx API supports comparing gene expression between tissues like brain and liver by retrieving median TPM levels across 54 distinct human tissues. This allows direct comparison of regulatory effects and expression patterns across tissue types.
