Alpha 1 Antitrypsin Deficiency
Understanding Alpha-1 Antitrypsin Deficiency
Alpha-1 is the common name for a genetic condition called alpha-1 antitrypsin deficiency. If you have Alpha-1, your body is unable to produce a protein known as alpha-1 antitrypsin, or A1AT for short. This protein plays an important role in protecting your lungs from damage due to excessive inflammation. Without this protein present in your blood, your lungs may weaken over time and place you at a higher risk for developing serious diseases, such as emphysema and chronic obstructive pulmonary disease (COPD). An abnormal amount of A1AT in the liver can also cause liver disease.

How is Alpha-1 Diagnosed?
Alpha-1 can only be diagnosed by a blood test. You and your doctor should talk about your risk for Alpha-1. If you have a family history of Alpha-1, COPD, emphysema, irreversible asthma, unexplained liver disease, or a skin disorder called necrotizing panniculitis, you should be tested for Alpha-1. If you are at risk, you will be given a simple blood test to confirm your diagnosis. Alpha-1 is a progressive disease, which means if it is left undiagnosed and untreated, it can get worse and may do more harm to your lungs and body over time.Learn More
How Alpha-1 Antitrypsin Works in the Body
Alpha-1 antitrypsin (A1AT) is a protein made in your liver. Its main function is to protect your lungs from inflammation caused by infection and inhaled irritants such as tobacco smoke. Alpha-1 occurs when there is a low level or insufficient amount of A1AT protein in the blood. When this happens, there is not enough A1AT traveling from the liver to your lungs. The low level of A1AT in the blood occurs because misfolded A1AT cannot be released from the liver at a normal rate. This leads to a buildup of A1AT in the liver that can cause liver disease. Alpha-1 is a progressive disease. Without treatment, Alpha-1 can get worse over time. It can also cause other serious lung diseases, such as COPD and emphysema.Learn More
