EQTL List Datasets

List available eQTL (expression Quantitative Trait Loci) datasets from the EBI eQTL Catalogue. Each dataset represents a study-tissue-quantification combination with measured genetic associations to gene expression. Returns dataset IDs, study labels, tissue types, sample sizes, and quantification methods (ge=gene expression, exon, tx=transcript, txrev=transcript ratio, leafcutter=splicing). Use dataset IDs with eQTL_get_associations for specific variant-gene associations.
