Liver disease has never been reported in individuals with AATD due to homozygous null alleles. Liver disease may occur throughout a person’s life. In children, liver disease may present only transiently or may be persistent, progressing to fibrosis and cirrhosis requiring liver transplant. Cholestatic jaundice and hepatitis can be observed in some newborns, while later during childhood individuals may experience an unexplained increase in aminotransferases, hepatomegaly, or on rare occasions, cirrhosis, and liver failure. Adults may show asymptomatic changes in transaminases, cirrhosis, and hepatocellular carcinoma. Liver disease in adults may occur in the absence of a history of neonatal or childhood liver disease. \\n\\nEmphysema is the most common manifestation of AATD. Pulmonary disease affects males and females equally, and the approximate age of diagnosis is 40-45 years. Individuals with null alleles are at risk of the most severe form of the associated disease, including emphysema. Individuals with the Pi*ZZ genotype have a high risk of emphysema, Pi*SZ have an increased risk for emphysema, and Pi*SS is not associated with a significant risk of emphysema. Active smoking is the most important additional risk factor for the development and course of lung function deficits and COPD. Individuals with AATD who smoke develop COPD 10-20 years earlier than smokers without AATD and they have a median survival time approximately 15 years less than individuals with AATD who are not smokers. Lung disease progression is more rapid than in non-AATP patients with COPD. However, smoking cessation can “normalize” this progression to that of AATD in never-smokers. \\n\\nMortality in individuals with AATD results primarily from respiratory diseases, followed by liver complications.
