Alpha-1 Antitrypsin Deficiency is a genetic condition where the body does not produce enough of the protein alpha-1 antitrypsin, which protects the lungs and liver from damage. This deficiency can lead to serious health issues, including lung diseases like emphysema and liver problems such as cirrhosis. The condition is inherited in an autosomal co-dominant manner, meaning that a person can inherit the deficiency from both parents. Diagnosis often involves blood tests to measure alpha-1 antitrypsin levels, and treatment may include lifestyle changes, medications, or in severe cases, liver transplantation.
