Alpha-1 antitrypsin deficiency (A1AD or AATD) is a genetic disorder that may result in lung disease or liver disease. [1] Onset of lung problems is typically between 20 and 50 years of age. [ 1 ] This may result in shortness of breath , wheezing , or an increased risk of lung infections .
About Alpha-1 Antitrypsin (AAT) and AAT Deficiency Alpha-1 antitrypsin deficiency is an autosomal disorder that results in disease of the lungs and liver, and afflicts roughly 10,000 patients ...

Alpha-1 antitrypsin or α 1-antitrypsin (A1AT, α 1 AT, A1A, or AAT) is a protein belonging to the serpin superfamily. It is encoded in humans by the SERPINA1 gene.A protease inhibitor, it is also known as alpha 1 –proteinase inhibitor (A1PI) or alpha 1-antiproteinase (A1AP) because it inhibits various proteases (not just trypsin). [5]
In medicine, protease inhibitor is often used interchangeably with alpha 1-antitrypsin (A1AT, which is abbreviated PI for this reason). [3] A1AT is indeed the protease inhibitor most often involved in disease, namely in alpha-1 antitrypsin deficiency.
Alpha-1 antitrypsin deficiency is a genetic risk factor that may lead to the condition presenting earlier. [9] When associated with significant airflow limitation, emphysema is a major subtype of chronic obstructive pulmonary disease (COPD), a progressive lung disease characterized by long-term breathing problems and poor airflow.
At Every Child Pediatrics, Luzietti says around 7,000 of her patients lost Medicaid, and the percentage of uninsured patients seeking treatment at her clinics grew from 8% to 15% during the unwinding.
Elastase is inhibited by the acute-phase protein α 1-antitrypsin (A1AT), which binds almost irreversibly to the active site of elastase and trypsin. A1AT is normally secreted by the liver cells into the serum. Alpha-1 antitrypsin deficiency (A1AD) leads to uninhibited destruction of elastic fibre by elastase; the main result is emphysema.
