Editing Approaches To Treat Alpha-1 Antitrypsin Deficiency, Derek M. Erion, Leah Y. Liu, Christopher R. Brown, Stephen I. Rennard, Humam Farah

Journal Articles: Pulmonary & Critical Care Med

TOPIC IMPORTANCE: Alpha-1 antitrypsin (AAT) deficiency is a genetic disorder most commonly due to a single G to A point mutation (E342K), leading to debilitating lung and/or liver disorders and is associated with increased mortality. The E342K point mutation causes a conformational change of the AAT protein resulting in its retention in liver hepatocytes. This reduces AAT secretion into the serum resulting in higher protease activities due to the lack of inhibition from AAT, causing damage to healthy lung tissue. The current standard of care for lung manifestations involves weekly IV augmentation therapy and is considered suboptimal for these patients. …
