Co-expression of intergenic CRSs with their closest annotated gene element according to modENCODE tiling array experiments [30]. A co-expression score of 1 indicates perfect positive co-expression, i.e. both CRS and closest gene are exclusively expressed together, −1 indicates perfect negative co-expression, i.e. both elements are only expressed individually, and a score of 0 indicates that the expression of CRS and closest gene were observed to be independent of each other
