To query GTEx tissue expression and eQTLs, use the GTEx REST API v2 endpoints with either the geneSymbol or gencodeId parameter to retrieve structured JSON containing median expression and significant regulatory variants.

Yes, you can retrieve sQTL data across 54 tissues by querying the GTEx REST API v2 endpoints. The workflow returns structured JSON for splicing regulation analysis while handling dataset versioning and pagination automatically.

Querying gtex_v10 and gtex_v8 datasets targets different GTEx data releases, specified via the datasetId parameter. Selecting the appropriate dataset version ensures you retrieve the correct tissue-specific expression and QTL data for your analysis.

Tissue-specific gene expression helps interpret GWAS loci by identifying which tissues are most affected by genetic variants, while eQTL and sQTL data reveal regulatory mechanisms underlying GWAS signals across the 54 GTEx tissues.

Yes, the GTEx API supports large-scale data retrieval for multiple genes by utilizing built-in pagination handling within the workflow, allowing systematic programmatic querying of expression and QTL datasets.

Limitations of GTEx API v2 for eQTL analysis include handling pagination constraints for large-scale downloads and strictly managing dataset version compatibility between gtex_v10 and gtex_v8 to ensure accurate data retrieval.
