Alpha-1 Antitrypsin Deficiency (AATD)

Understanding Alpha-1 Antitrypsin Deficiency

Alpha-1 Antitrypsin Deficiency (AATD) is a genetic disorder characterized by low levels of the protein alpha-1 antitrypsin (AAT) in the blood. AAT, produced by the liver, is essential for protecting the lungs and other tissues from damage caused by enzymes such as neutrophil elastase. When AAT levels are insufficient, it can lead to lung conditions like emphysema or chronic obstructive pulmonary disease (COPD) and liver diseases, including cirrhosis.

Common Signs and Symptoms of Alpha-1 Antitrypsin Deficiency:

• Respiratory Symptoms:

  • Shortness of Breath: Difficulty breathing, particularly during physical activity.
  • Chronic Cough: A persistent cough that may produce phlegm.
  • Wheezing: A whistling sound when breathing.

• Liver-Related Symptoms:

  • Fatigue: Persistent tiredness or decreased energy levels.
  • Jaundice: Yellowing of the skin and eyes.
  • Abdominal Discomfort: Pain or swelling in the upper right side of the abdomen.
