Alpha-1 Antitrypsin Test Results Receiving test results Many AAT test results are available within a few business days, but the exact timeline depends on the type of testing that is done. Because different kinds of laboratory analysis can be performed, you should check with your doctor about the...

alpha(1)-Antitrypsin deficiency (AATD) is an autosomal-codominant genetic disorder that predisposes individuals to the development of liver and lung disease. AATD is greatly underrecognized and underdiagnosed. Early identification allows preventive measures to be taken, the most important of which is th...
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. Exposur...
Alpha-1-antitrypsin deficiency (A1ATD): What is A1AT? A1AT is a serine protease inhibitor secreted primarily in liver parenchymal cells and to a lesser extent in macrophages. It protects tissues from enzymes of inflammatory cells by inactivating especially neutrophil elastase (and also a variety ...
Alpha1-antitrypsin deficiency (AATD) was first described by Laurell and Eriksson in 1963. Laurell noted the absence of the band of alpha1- protein in 5 of 1500 serum protein electrophoreses (SPEP) submitted to his laboratory in Sweden.
Results: Since the original description of AATD by Laurell and Eriksson in 1963, testing methods have undergone major changes. Currently, alpha-1 antitrypsin protein is quantified by immunologic measurement in serum, and the phenotype is characterized by isoelectric focusing and/or targeted genotyping ...
While some mutations in SERPINA1 completely abolish the gene message meaning no protein, others like the most common mutation, called Pi*Z, results in a misfolded alpha-1 antitrypsin protein being made. 两种突变:一种是导致蛋白不能产生,另一个是导致蛋白的错误折叠。 Misfolded alpha-1 antitrypsin ca...
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...
Vertex Announces Primary Endpoint Achieved in Phase 2 Study of VX-864 in Alpha-1 Antitrypsin Deficiency - Treatment with VX-864 led to a statistically significant increase from baseline in plasma functional AAT levels as compared to placebo and was generally well tolerated - ...
