Eight HARs showed differences in their enhancer activity when the human mutations were present.4 These differences modify how genes were expressed in the developing limb (HAR2, 2xHAR114), eye (HAR25), and central nervous system (2xHAR142, 2xHAR238, 2xHAR164, 2xHAR170, ANC516 / HARE5).4, 10 Because relatively few time points have been examined, it is likely that an even higher percentage of the tested HARs are active enhancers at some point during embryonic development or in adult tissues, possibly with human - chimp differences.
