Alpha-1-antitrypsin deficiency (A1ATD; MIM 613490) is an autosomal recessive disorder caused by mutations in the SERPINA1 gene. This gene encodes alpha-1-antitrypsin, an inhibitor of serine proteases. Its primary target is elastase and its main function is to protect the lower respiratory tract against proteolytic destruction by human leukocyte elastase. Patients with A1ATD develop emphysema with an age of onset around 35 years for smokers and 45 for nonsmokers.read more
