Alpha-1-antitrypsin deficiency (AATD) is a rare genetic disorder associated with the development of liver and lung disease. AAT is a 52-kD glycoprotein, produced mainly by hepatocytes and secreted into the blood. Agglomeration of the AAT-protein in hepatocytes can result in liver disease. ...
Alpha-1 antitrypsin(抗胰蛋白酶)deficiency is a genetic disorder(遗传病)in which a protein called alpha-1antitrypsin is defective or absent, and it causes lung and liver disease. α抗胰蛋白酶缺乏症是一种遗传性疾病,患者体内的一种叫做α抗胰蛋白酶的蛋白质出现了问题或者含量减少了,最终导致肺和肝脏...

More than 90 phenotypic variants of alpha1-antitrypsin deficiency have been identified, but one phenotype, PiZZ, is responsible for nearly all cases of AAT deficiency emphysema and liver disease. PiZZ phenotype serum levels range from 3.4-7 µmol/L, about 10-20% of the reference range levels...
Alpha-1 antitrypsin deficiency (AATD) is one of the most common potentially life-threatening genetic disorders. It predisposes patients to lung and liver damage, and both organs constitute the most prevalent causes of AATD-related mortality.1 AATD arises from mutation-based misfolding of the anti-...
An alpha 1-antitrypsin level obtained shortly after biopsy was spuriously within the lower limits of the physiologic range. Further investigation demonstrated a homozygous Z phenotype, the classic protease inhibitor variant described in alpha 1-antitrypsin deficiency. A repeat liver biopsy confirmed the ...
Enhanced phenotypic expression of alpha-1-antitrypsin deficiency in an MZ heterozygote with chronic hepatitis C. be heterozygous for alpha1-antitrypsin deficiency (PiMZ phenotype) after diagnostic PAS-positive, diastase-resistant globules were detected in a liver biopsy...

Alpha-1 antitrypsin deficiency (AATD)-mediated liver disease is a toxic “gain-of-function” inflammation in the liver associated with intracellular retention of mutant alpha-1 antitrypsin. The clinical presentation of the disease includes fibrosis, cirrhosis and liver failure. However, the pathogenic ...
Liver transplantation (LT) is the therapeutic option for end-stage liver disease associated with alpha1 antitrypsin (A1AT) deficiency. The aim of the present retrospective study was to report on long-term outcomes following LT for A1AT deficiency. Methods The medical records of 90 pediatric and ...
Alpha-1-antitrypsin deficiency is the most common inborn error of metabolism leading to liver transplantation, and the second cause of liver transplantation in children after biliary atresia. The authors report the case of a 6-year-old girl, who was suffering from end-stage liver disease secondary...
