Extractions: Mendelian inheritance consistent with deficiency gene. The gene for Alpha-1-antitrypsin is present on chromosome 14 and expressed in the hepatocyte and in the mononuclear phagocyte. Two Parental alleles, Z type and S type, are codominantly expressed. Therefore phenotypes, null-null, ZZ, and SZ, are responsible for emphysema. Pathophysiology: Radiographically, severe emphysematous changes are present predominantly in the lower lobes. There may be increased vascularity of the upper lobes. Evidence of pulmonary hypertension and right ventricular enlargement is often present. The plain chest x-ray may not be particularly abnormal in the early stages.

Alpha-1 Antitryspin Deficiency What is alpha-1 antitrypsin deficiency? Alpha-1 antitrypsin deficiency is a disorder in which there are inadequate levels of alpha-1 antitrypsin in the bloodstream. Without sufficient alpha-1 antitrypsin, the lungs are vulnerable to damage from neutrophil elastase.

Extractions: A rare cause of common problems The same illness may have different causes, some common, and some uncommon. Take emphysema, for example, most often it's smoking that causes this unpleasant lung disease, but the effects of working down a mine for many years may also be responsible. Liver cirrhosis is commonly the result of drinking too much alcohol, but it may also be caused by hepatitis infection. Then there are the more rare, but equally important causes of these diseases, such as Alpha-1-antitrypsin deficiency. Inherited from both parents Alpha-1 Antitrypsin (AAT) deficiency is an inherited condition where a person lacks a protein known as alpha-1 antitrypsin. There may be low levels of the protein but it doesn't work properly. Alpha-1-antitrypsin (A-1-A) is made in the liver. It is particularly important in the lung where it mops up another enzyme called neutrophil elastase. This enzyme normally digests damaged or ageing lung cells, foreign particles and bacteria, but has the potential to harm healthy lung tissue. In Alpha-1 Antitrypsin deficiency, neutrophil elastase cannot be neutralised and so is able to destroy healthy tissue.

Help Alpha-1 antitrypsin deficiency Alpha-1 antitrypsin deficiency is an inherited disorder that can cause lung disease in adults and liver disease in adults and children. The first signs of lung disease caused by alpha-1 antitrypsin deficiency usually appear between ages 20 and 40. The earliest symptoms are shortness of breath following mild activity, reduced ability to exercise, and wheezing. Other symptoms can include unintentional weight loss, recurring respiratory infections, fatigue, a barrel-shaped chest, rapid heartbeat upon standing, and vision abnormalities. Smoking or exposure to tobacco smoke accelerates the appearance of symptoms and damage to the lungs. About 10 percent of infants and 15 percent of adults also have liver damage caused by alpha-1 antitrypsin deficiency. Symptoms of liver disease can include a swollen abdomen, coughing up blood, swollen feet or legs, and yellowing of the skin and whites of the eyes (jaundice).

Authors Alpha-1-Antitrypsin Deficiency ALPHA-1-ANTITRYPSIN DEFICIENCY [introduction] [discovery and prevalence] [serpins] serpin polymerisation ... [case study] INTRODUCTION: Misfolding of proteins during their synthesis can initiate an ordered polymerisation, which leads to the aggregation of the protein within the cell. The most common and severe form of alpha-1-antitrypsin deficiency is caused by the Z mutation, a single base substitution (Gul-342-Lys) in the alpha-1-antitrypsin gene. This slows the rate of protein folding in the cells of synthesis, allowing the accumulation of an intermediate which then polymerises (James EL et al 1999), impeeding its release, and leading to plasma deficiency. Alpha-1-antitrypsin is a serpin Serpin polymerisation results in a variety of diseases, the best studied being lung destruction and sometimes liver damage that results from mutations of the alpha-1-antitrypsin gene. It is now known that serpin polymerisation involves interaction of one serpin molecule with the beta-sheet of another of the same type: the extensive knowledge of this mechanism may help in the development of beta-strand blockers to prevent the self-association of these proteins (Carrell RW, Lomas DA 1997), and this may be applicable to research into the other highly topical conformational diseases, such as Creutzfeldt-Jakob Disease.

Extractions: Alpha-1-antitrypsin deficiency is an inherited disorder which usually affects the lungs. The information presented here is intended to answer your questions and provide you with a better understanding of this rare condition. What is alpha-1-antitrypsin? Alpha-1-antitrypsin is a protein which is produced by the liver and enters the blood stream. Its main role is to protect the lungs from destruction by other proteins called enzymes. Enzymes are found in all parts of the body and are needed for digestion to ensure that chemical reactions in the body proceed normally. Enzymes are also involved in areas of inflammation and tissue injury where they occur as a result of cell damage. What is alpha-1-antitrypsin deficiency? Alpha-1-antitrypsin deficiency is present when there is less than the normal amount of this protein in the blood. It becomes important only when the concentration in the blood is less than 20% to 30% of what we would normally expect. When this deficiency occurs, the lung is poorly protected from destructive enzymes and loss of lung tissue occurs, leading to a condition called emphysema. Once in every 2500 people in Australia has severe alpha-1-antitrypsin deficiency (levels below 20% of normal). This translates to nearly 7000 Australians with alpha-1-antitrypsin deficiency.

Extractions: Causes, incidence, and risk factors: Alpha-1 antitrypsin deficiency results from a genetic defect. The mechanism that causes associated liver disease and emphysema in some people with this deficiency is not known, however some evidence suggests that it may be related to inflammation. Approximately 75% of adults with severe deficiency will develop emphysema, which often begins before 40 years of age. Smoking can increase risk.
