WebThe genetic changes cause too little or no working alpha-1 antitrypsin protein (AAT) to be made. AAT is made in the liver cells and sent through the bloodstream to the lungs where it helps protect the lungs from damage. Having low levels of AAT (or no AAT) may lead the lungs to become damaged. A build-up of abnormal AAT may cause liver damage.
