What Is Alpha-1-Antitrypsin Deficiency?
Alpha-1-antitrypsin deficiency is a rare genetic disorder that affects the lungs, liver, and other organs. It occurs when there is a deficiency of a protein called alpha-1-antitrypsin, which is produced by the liver and helps to protect the lungs from damage. This protein is essential for maintaining healthy lung function and preventing the breakdown of lung tissue.
Causes and Risk Factors
The deficiency is usually inherited in an autosomal recessive pattern, meaning that a person needs to inherit two copies of the mutated gene (one from each parent) to develop the condition. Carriers of the mutated gene, who have one copy of the gene, are generally healthy but can pass the gene to their offspring. The risk of developing alpha-1-antitrypsin deficiency is higher in people of Northern European descent.
How Alpha-1-Antitrypsin Deficiency Affects the Body
In people with alpha-1-antitrypsin deficiency, the lack of this protein leads to the breakdown of lung tissue, causing emphysema, a condition characterized by shortness of breath, wheezing, and coughing. The deficiency can also cause liver disease, as the liver becomes inflamed and scarred, leading to cirrhosis and liver failure.
Alpha-1-Antitrypsin Deficiency Symptoms
The symptoms of alpha-1-antitrypsin deficiency can vary in severity and may not appear until adulthood. Common symptoms include:
- Shortness of breath (dyspnea) or feeling winded even when doing simple tasks
- Wheezing or coughing, which can be persistent and severe
- Fatigue, which can be debilitating and affect daily life
- Recurring respiratory infections, such as bronchitis or pneumonia
- Liver problems, including jaundice, abdominal pain, and swelling
If you’re experiencing any of these symptoms, it’s essential to consult a healthcare professional for proper diagnosis and treatment. Early detection and management can significantly improve the quality of life for individuals with alpha-1-antitrypsin deficiency.

Causes and Risk Factors of Alpha-1-Antitrypsin Deficiency
Alpha-1-antitrypsin deficiency is a genetic disorder that affects the production of alpha-1-antitrypsin, a protein that helps protect the lungs and liver from damage. The deficiency is caused by mutations in the SERPINA1 gene, which codes for the alpha-1-antitrypsin protein.
Genetic Mutations
The mutations in the SERPINA1 gene can be inherited from one’s parents in an autosomal codominant pattern. This means that a single copy of the mutated gene is enough to cause the deficiency. The mutations can affect the production or function of the alpha-1-antitrypsin protein, leading to a deficiency.
Risk Factors
Certain individuals are at a higher risk of developing alpha-1-antitrypsin deficiency. These include:
- Family history: Individuals with a family history of alpha-1-antitrypsin deficiency are at a higher risk of developing the condition.
- European ancestry: Alpha-1-antitrypsin deficiency is more common in people of European ancestry, particularly those of Northern European descent.
- Smoking: Smoking can exacerbate the symptoms of alpha-1-antitrypsin deficiency and increase the risk of lung disease.

- Chest X-ray or CT scan: These imaging tests can help identify lung damage or disease.
Diagnostic Criteria
A diagnosis of alpha-1-antitrypsin deficiency is typically made based on the following criteria:
- A low level of alpha-1-antitrypsin in the blood (less than 11 ΞΌM).
- The presence of mutations in the SERPINA1 gene.
- Signs of lung or liver disease on imaging tests.
Early diagnosis and treatment of alpha-1-antitrypsin deficiency can help slow the progression of the disease and improve quality of life.
Alpha-1-Antitrypsin Deficiency Treatment and Management
Alpha-1-antitrypsin deficiency is a genetic disorder that affects the lungs, liver, and other organs. While there is no cure for this condition, various treatment options and management strategies can help alleviate symptoms, slow disease progression, and improve quality of life.
Augmentation Therapy
The primary goal of augmentation therapy is to increase the levels of alpha-1-antitrypsin in the blood. This is achieved through weekly intravenous infusions of alpha-1-antitrypsin protein. This therapy has been shown to slow the progression of lung disease and improve lung function.
Lung Transplantation
In severe cases of alpha-1-antitrypsin deficiency, lung transplantation may be necessary. This surgical procedure involves replacing the diseased lungs with healthy ones from a donor. Lung transplantation can significantly improve lung function and overall quality of life.
Management of Liver Disease
Alpha-1-antitrypsin deficiency can also affect the liver, leading to liver disease and cirrhosis. Management of liver disease involves monitoring liver function, treating liver-related complications, and considering liver transplantation in severe cases.
