Alpha-1 Antitrypsin Deficiency
by Yael Rosenberg, RN
Description
Alpha-1 Antitrypsin (AAT) Deficiency is an autosomal recessive
disorder that is caused by a mutation of the SERAPINA 1 (PI) gene on
chromosome 14. The liver in individuals with this disorder does not
produce enough of the protein AAT which is a protease inhibitor
whose function is to protect the lungs and liver from damage.
Reduction or lack of this principle protease inhibitor in the blood
gives rise to deterioration of the lung tissue and increases risk of
severe lung disease. In addition buildup of abnormal AAT in the
liver can result in liver disease.
Symptoms
• Shortness of breath on minimal exertion
• Chronic productive cough
• Repeated respiratory infections
• Affected people often develop emphysema
• Unintentional weight loss
• Approximately 10% of infants develop liver disease which
frequently causes jaundice 15% of adults develop
cirrhosis of the liver due to scar formation which has the
following symptoms:
• Ascites
• Edema of feet or legs
• Jaundice
There is a higher incidence for those affected by Alpha-1
Antitrypsin (AAT) Deficiency to develop a type of liver cancer
called hepatocellular carcinoma
Incidence and Carriers
Most common fatal genetic disorder worldwide
Carrier Frequency: PiS allele: 1 in 9 – 1 in 12 among
Caucasians.
PiZ allele: 1 in 30 – 1 in 40 among Caucasians.
PiZ allele prevalence among Ashkenazi Jewish ancestry is 1 in 92
Disease Frequency: 1,500 – 3,500 individuals of European Ancestry
Uncommon in individuals of Asian descent
Many people with Alpha-1 Antitrypsin (AAT) Deficiency are believed
to be undiagnosed especially those with the common diagnosis of
COPD- Chronic Obstructive Pulmonary Disease.
Treatment
• Augmentation Therapy: Injection of alpha -1-antitrypsin
from blood of healthy donors.
• Gene therapy: Currently under research
• Organ transplantation when damage to lungs or liver is
extensive.
• Symptomatic treatment: Medications for bronchial symptoms.
Quitting smoking is vital
• Supportive treatment: Improving lung function with
exercise, and deep breathing, and supplemental oxygen when
needed.
Testing
In 2003 The American Thoracic Society and The European Respiratory
Society set comprehensive guidelines for the genetic diagnosis of
alpha-1-antitrypsin deficiency. The guidelines focus on who should
be tested and why.
It is recommended that the following individuals undergo genetic
testing for AAT deficiency:
• Individuals afflicted with COPD, emphysema, unexplained
liver disease, necrotizing paniculitis, vasculitis, bronchiectasis.
• Those individuals who have family members with AAT
deficiency or unexplained liver disease or COPD
• Those living in countries where the prevalence of AAT
deficiency is high should undergo carrier screening tests.
The following test assist with the diagnosis:
• Alpha-a-antitrypsin levels in the blood
• Arterial blood gases
• Chest X-ray
• CT scan of the chest
