1 antitrypsin deficiency is not an autoimmune disease, but a genetic disorder caused by mutations in the SERPINA1 gene.<\/p><p>This gene controls production of alpha-1 antitrypsin, a protein made in the liver that protects the lungs from inflammation caused by enzymes such as neutrophil elastase.<\/p><p>When AAT levels are low or dysfunctional:<\/p><ul><li>lung tissue becomes vulnerable to damage<\/li><li>abnormal protein may accumulate in the liver<\/li><li>both respiratory and liver diseases can develop<\/li><\/ul><h2><strong>Symptoms of Alpha-1 Antitrypsin
