Familial A1AT deficiency leads to predominantly unrestricted proliferation of neutrophil-mediated elastase in the tissues of the lung, causing extensive collateral damage and subsequent emphysema-like symptoms in adults. Alternatively, neonatal accumulation of dysfunctional A1AT in the liver causes the production of abnormal polymers that damage the surrounding tissues of the liver.
