Regarding the locational relationships between the eQTL and the gene, 102 of the eQTLs were cis-acting (within 1 Mb upstream or downstream of the gene), and 5 were trans-acting, of which 4 were located on a different chromosome from the gene that they influenced. When the genome was divided into 3 segments (i.e., upstream, intragenic, and downstream), 69 cis-acting eQTL regions covered multiple segments that included the intragenic segments, 13 were confined to upstream segments, 7 were confined to downstream segments, and 13 were confined to intragenic segments.
