Using farm pigs from the PigGTEx resource, we apply quantile regression to reveal context-dependent genetic effects on gene expression across tissues. We identify quantile-specific expression quantitative trait loci (eQTLs) missed by standard linear models that preferentially localize to distal regulatory elements and three-dimensional genome architecture, in contrast to the promoter-proximal bias of canonical eQTLs. Genes with quantile-dependent eQTLs are more intolerant to loss-of-function variants and exhibit distinct patterns of enrichment in GO functional categories, indicating their likely functional significance. Cross-species comparisons reveal substantial overlap between pig and human eGenes across tissues, indicating conservation of regulatory architecture. Notably, many quantile-specific eQTLs influence tail expression states and involve genes relevant to human disease. For example, we identify a cis-eQTL affecting the conserved transcriptional regulator BCL6B in pig blood that modulates enhancer activity and reduces expression at lower quantiles. In contrast, BCL6B is minimally expressed in resting human blood and lacks detectable cis-regulatory variation under baseline conditions, consistent with its reported induction during immune activation. These findings demonstrate that pig eQTL maps can reveal context-dependent regulatory variation at loci that remain silent or weakly variable in human cohorts.<\/jats:p>","DOI":"10.1093\/genetics\/iyag234","type":"journal-article","created":{"date-parts":[[2026,8,31]],"date-time":"2026-08-31T19:21:47Z","timestamp":1788204107000},"source":"Crossref","is-referenced-by-count":0,"title":["Context-dependent
