Massively parallel reporter assay (MPRA) studies converge on some of the same active and differentially active human accelerated regions (HARs). The 441 HARs that have been tested in three MPRA studies were compared for consistency of results [Uebbing et al. (66), Girskis et al. (22), Whalen et al. (71)]. (a) Counts of HARs that were active in one, two, or all three studies. (b) Counts of HARs where the human and chimpanzee alleles were differentially active in one, two, or all three studies.
