Alpha-1 antitrypsin (AAT) deficiency is a genetic condition that affects the lungs and liver. It is caused by mutations in the SERPINA1 gene, which is responsible for producing the AAT protein. AAT is mainly produced by the liver and helps protect the lungs from damage by neutrophil elastase, an enzyme that can break down lung tissue. In individuals with AAT deficiency, the mutations in the SERPINA1 gene result in reduced or absent production of AAT, leading to an increased risk of developing lung and liver diseases.
AAT deficiency is inherited in an autosomal codominant manner, which means that both copies of the SERPINA1 gene are affected. There are several different alleles of the SERPINA1 gene, and each allele is associated with a different level of AAT production. The most common allele associated with AAT deficiency is called S, and it results in a moderate reduction in AAT production. The Z allele is the rarest and causes the most severe form of AAT deficiency, with significantly reduced AAT levels.
The severity of AAT deficiency and the associated lung and liver diseases can vary widely among individuals. Some people may develop symptoms at a young age, while others may remain asymptomatic until later in life. AAT deficiency is a known risk factor for developing chronic obstructive pulmonary disease (COPD), particularly in individuals who smoke or are exposed to other lung-damaging substances. Other lung diseases, such as asthma and bronchiectasis, can also be associated with AAT deficiency.
There are several resources available for individuals and families affected by AAT deficiency. The Alpha-1 Foundation, a non-profit organization based in the United States, provides support, advocacy, and information on AAT deficiency and related lung and liver diseases. The National Center for Biotechnology Information offers additional information and references on AAT deficiency through its online databases, including PubMed, OMIM, and Gene.
Clinical trials are also conducted to further our understanding of AAT deficiency and develop new treatment options. ClinicalTrials.gov is a valuable resource for finding information on ongoing clinical trials involving AAT deficiency and other genetic diseases. Genetic testing is available to diagnose AAT deficiency, and individuals with a family history of the condition or those showing symptoms should consider getting tested. Early diagnosis can help guide appropriate medical management and treatment options.
In summary, Alpha-1 antitrypsin deficiency is a rare genetic condition that can cause lung and liver diseases. It is caused by mutations in the SERPINA1 gene, resulting in reduced or absent production of the AAT protein. The severity of the condition and associated diseases can vary, and individuals with AAT deficiency may benefit from the support and resources provided by organizations like the Alpha-1 Foundation.
Frequency
Clinical testing for alpha-1 antitrypsin deficiency is available from a few laboratories worldwide. The frequency of alpha-1-antitrypsin deficiency varies among different populations and ethnic groups. The alpha-1 antitrypsin deficiency gene (SERPINA1) has several names and aliases in the medical catalog of genes and genetic disorders, including SERPINA1, A1AT, alpha-1-antitrypsin, alpha-1-antiprotease, AATD, and more.
Alpha-1 antitrypsin deficiency is a rare condition, affecting approximately 1 in every 1,500 to 3,500 individuals in the United States. The severity of the disease can vary widely among individuals. Not all individuals with alpha-1 antitrypsin deficiency will develop clinical symptoms or related diseases.
Alpha-1 antitrypsin deficiency is associated with the development of various diseases, such as chronic obstructive pulmonary disease (COPD) and liver diseases. Research studies have shown that individuals with two copies of the defective SERPINA1 gene are at an increased risk of developing these diseases.
According to the Alpha-1 Foundation, alpha-1 antitrypsin deficiency affects an estimated 100,000 individuals worldwide. The inheritance pattern of alpha-1 antitrypsin deficiency is autosomal codominant, meaning that both copies of the SERPINA1 gene contribute to the condition. The deficiency is caused by mutations in the SERPINA1 gene, leading to reduced levels or abnormal function of alpha-1 antitrypsin protein in the body.
Patients with alpha-1 antitrypsin deficiency may experience clinical symptoms, such as shortness of breath, wheezing, and recurrent chest infections. It is important for patients to learn about additional resources and support, such as patient advocacy organizations and clinical trials, to manage their condition effectively.

Causes
Alpha-1 antitrypsin deficiency (AATD) is a rare genetic condition that affects the lungs and liver. It is caused by mutations in the SERPINA1 gene, which provides instructions for making the alpha-1 antitrypsin protein. This protein helps protect the lungs from damage caused by enzymes released by white blood cells.
There are different alleles (versions) of the SERPINA1 gene, and some are associated with a higher risk of developing AATD. The severity of the condition is determined by the type of allele a person inherits.
Most people with AATD inherit two abnormal alleles, one from each parent. The most common abnormal allele associated with AATD is called the Z allele. People with two Z alleles have the highest risk of developing severe lung and liver disease.
Other alleles, such as the S and I alleles, can also cause AATD, but they are not as common or as severe as the Z allele.
Clinical studies and research have shown that individuals with AATD are at increased risk for developing lung conditions such as chronic obstructive pulmonary disease (COPD), emphysema, and bronchiectasis. Liver diseases, such as cirrhosis and hepatocellular carcinoma, are also associated with AATD.
The World Health Organization estimates that about 3-5 percent of patients with COPD and 1-2 percent of patients with liver disease have AATD. However, AATD is often underdiagnosed and misdiagnosed, so the actual prevalence may be higher than reported.
Testing for AATD can be done through genetic testing, which can identify the presence of abnormal alleles. This information can help healthcare providers determine the appropriate treatment plan for individuals with AATD.
There are resources available for individuals with AATD and their families, including advocacy groups and support networks. The Alpha-1 Foundation, based in Miami, Florida, provides information and support for patients and their families. The organization also funds research and clinical trials to advance the understanding and treatment of AATD.
Additional information about AATD can be found in scientific articles and research studies. The National Library of Medicine’s PubMed database and the Online Mendelian Inheritance in Man (OMIM) catalog are valuable resources for finding articles and references related to AATD and its associated conditions.
Learn more about the gene associated with Alpha-1 antitrypsin deficiency
Alpha-1 antitrypsin deficiency is a rare genetic condition associated with the alpha-1 antitrypsin gene. This gene provides instructions for making a protein called alpha-1 antitrypsin, which is produced mainly in the liver and released into the bloodstream. Alpha-1 antitrypsin helps protect the body’s tissues from damage caused by an enzyme called neutrophil elastase, which is produced by white blood cells.
Alpha-1 antitrypsin deficiency occurs when there are changes (mutations) in the alpha-1 antitrypsin gene that lead to the production of an abnormal protein or insufficient amounts of the protein. These mutations can result in alpha-1 antitrypsin protein being trapped in liver cells, preventing it from reaching the lungs where it is needed. This can cause liver disease and lung disease, including chronic obstructive pulmonary disease (COPD).
There are different alleles, or versions, of the alpha-1 antitrypsin gene that can impact the production and function of the protein. The two most common alleles associated with alpha-1 antitrypsin deficiency are called M and Z. The M allele is considered normal, while the Z allele can result in reduced levels of alpha-1 antitrypsin in the bloodstream.
Alpha-1 antitrypsin deficiency affects people worldwide, but its frequency varies among different populations. In some populations, such as those of European descent, it is estimated to affect around 1 in 2,000 individuals. The condition is less common in other populations.
Clinical testing for alpha-1 antitrypsin deficiency can be conducted using various methods, including blood tests and genetic testing. These tests can help diagnose the condition and determine the specific gene mutations present.
In addition to clinical testing, there are resources available for individuals and healthcare professionals to learn more about alpha-1 antitrypsin deficiency. Organizations such as the Alpha-1 Foundation and the Alpha-1 Association provide information, support, and advocacy for patients and their families. There are also research centers, such as the Alpha-1 Center at the University of Washington in Seattle, that focus on studying and developing treatments for alpha-1 antitrypsin deficiency.
For more information about alpha-1 antitrypsin deficiency, its causes, and associated diseases, you can refer to scientific articles and publications. References such as the Online Mendelian Inheritance in Man (OMIM) database, PubMed, and clinicaltrial.gov can provide valuable information on the latest research and clinical trials related to this condition.
Inheritance
Alpha-1 antitrypsin deficiency is a genetic condition, which means it is inherited from one or both parents. It is caused by mutations in the SERPINA1 gene, located on chromosome 14. This gene provides instructions for producing alpha-1 antitrypsin, a protein that protects the body’s tissues from enzymes released by white blood cells. When the SERPINA1 gene is mutated, it produces an abnormal form of alpha-1 antitrypsin that cannot function properly.
Alpha-1 antitrypsin deficiency is inherited in an autosomal co-dominant manner. This means that a person affected by the condition has inherited one abnormal gene copy from each parent. Individuals who inherit only one abnormal gene copy are carriers of the condition and usually do not show any symptoms. However, they may have a higher risk of developing lung or liver problems later in life.
The severity of alpha-1 antitrypsin deficiency can vary depending on the specific mutations inherited. Some mutations result in a complete absence of alpha-1 antitrypsin, while others lead to a reduced amount of functional protein. The more copies of the abnormal gene a person has, the more severe the condition is likely to be.
Alpha-1 antitrypsin deficiency is associated with an increased risk of developing certain diseases, particularly pulmonary and liver diseases. It is strongly associated with the development of chronic obstructive pulmonary disease (COPD) at an early age, especially in individuals who smoke. Liver problems, such as cirrhosis and liver cancer, can also occur in individuals with the condition.
Research and scientific studies have provided valuable information about the inheritance and associated diseases of alpha-1 antitrypsin deficiency. They have also led to the development of genetic testing for the condition, which can identify individuals at risk and help guide treatment decisions.
For more information about alpha-1 antitrypsin deficiency, its inheritance, and associated diseases, you can visit reliable resources such as PubMed, OMIM, and the Alpha-1 Foundation. These resources provide access to articles, clinical guidelines, and other valuable information related to this condition.
Other Names for This Condition
Alpha-1 antitrypsin deficiency is also known by the following names:
- Alpha-1-antitrypsin deficiency
- Alpha-1 antiprotease deficiency
- A1AD
- AATD
- A1AT deficiency
- Alpha-1 PI deficiency
- Alpha-1 protease inhibitor deficiency
- Alpha-1 proteinase inhibitor deficiency
This condition is a rare genetic disorder that causes reduced levels of a protein called alpha-1 antitrypsin (AAT) in the blood. It is estimated that about 1 in 2,000 to 5,000 individuals in the general population has this deficiency.
Alpha-1 antitrypsin is primarily produced in the liver and plays a role in protecting the lungs from damage caused by enzymes released by certain cells in the lungs. When there is not enough alpha-1 antitrypsin, these enzymes can cause lung damage, leading to conditions such as chronic obstructive pulmonary disease (COPD).
The severity of alpha-1 antitrypsin deficiency can vary among individuals. Some may have no symptoms, while others will develop lung diseases at a young age. Inheritance of the condition follows an autosomal co-dominant pattern, meaning a person inherits two copies of the gene, one from each parent.
Clinical studies and research have identified different alleles of the alpha-1 antitrypsin gene that are associated with alpha-1 antitrypsin deficiency. The most common allele associated with the deficiency is called PiZZ, which occurs in approximately 90 percent of affected individuals. Other alleles, such as PiSZ and PiMM, are also associated with the condition but are less common.
Testing for alpha-1 antitrypsin deficiency can be done by measuring the levels of alpha-1 antitrypsin in the blood and by genetic testing to identify specific alleles. Genetic testing can also be useful for family members of individuals with the deficiency to determine if they are carriers.
Alpha-1 antitrypsin deficiency is often diagnosed in individuals who develop lung diseases, such as COPD, at a young age or have a family history of the condition. Clinical trials and research studies are ongoing to better understand the causes, diagnosis, and management of this condition.
