Abstract Background Raised activity of the renin-angiotensin system RAS may both amplify inflammatory and free radical responses and decrease tissue metabolic efficiency and thus enhance cerebral injury in the preterm infant. The angiotensin-converting enzyme ACE DD genotype is associated with raised ACE and RAS activity as well as potentially adverse stimuli such as inflammation. The DD genotype has been associated with neurological impairments in the elderly and thus may be also associated with poorer motor or cognitive development amongst children .
