Classical alpha-1 antitrypsin (a1AT) deficiency is an autosomal recessive disease associated with an increased risk of liver disease in adults and children, and with lung disease in adults (Teckman and Jain, Curr Gastroenterol Rep 16(1):367, 2014).

In individuals with AAT deficiency (AATD), AAT is retained in liver cells, which predisposes them to liver disease, and does not reach lung tissues through circulation, where it normally acts as the primary natural regulator of proteolytic activity in the pulmonary tissues, which thus leads to lung disease.
