What is it?

Alpha 1-Antitrypsin Deficiency is an inherited genetic condition where a person has low blood levels of a protein known as the alpha-1 antitrypsin protease inhibitor (called Alpha-1 PI or AAT). Alpha 1-Antitrypsin Deficiency causes an increased risk of chronic obstructive pulmonary disease (COPD) in the form of emphysema and, less frequently other diseases. It is often misdiagnosed, but a blood test can confirm the condition.

What causes it?

• Genetic inheritance from both parents.
• Smoking is not a cause, but can accelerate the prevalence of emphysema symptoms.
