Alpha-1-antitrypsin (A1AT) deficiency is an autosomal hereditary disorder associated with a
major reduction in serum A1AT levels. Clinically, A1AT deficiency is associated with
emphysema in adults and, less commonly, liver disease in neonates. A1AT is a 52-kDa, 394-
amino acid, single-chain glycoprotein normally present in serum at 150 to 350 mg/dl. The
A1AT gene, composed of seven exons dispersed over 12 kb of chromosomal segment
