Alpha-1-antitrypsin is a protein coded for by a gene, referred to as PI, located on the long arm of chromosome 14. That certain forms of premature emphysema had an inherited basis was first postulated by Laurell, Eriksson, and Axelsson in 1965 (1) . Electrophoretic variants of α1AT ...
Another, more common cause of COPD is smoking, and if someone with alpha-1 antitrypsin deficiencyalso smokes, they tend to get an earlier onset of COPD than they have otherwise, an exampleof a gene-environment interaction. 吸烟可能会导致COPD的发生这大家知道的,如果吸烟加抗胰蛋白酶缺乏?←_← ...
Alpha-1 antitrypsin deficiency (AATD) is a rare genetic disease that results from mutations in the alpha-1 antitrypsin (AAT) gene. The mutant AAT protein aggregates and accumulates in the liver leading to AATD liver disease, which is only treatable by liver transplant. The PiZ transgenic mouse...

Alpha-1 antitrypsin deficiency is an autosomal co-dominant disorder caused by mutations of the highly polymorphic SERPINA1 gene. This genetic disorder still remains largely under-recognized and can be associated with lung and/or liver injury. The laboratory testing for this deficiency typically comprises...
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.

Alpha-1 antitrypsin deficiency (A1AD or AATD) is an inherited genetic disorder that occurs due to the mutation of the gene, Serpina1. This results in insufficient levels of alpha-1 antitrypsin (A1AT or AA), which is a protein that protects the lungs. Wit
The emphysema results from excessive elastin degradation by neutrophil elastase as a result of the severe deficiency of its major inhibitor amp;alpha;1-antitrypsin (AAT). The AAT expression is determined by the SERPINA1 gene which expresses codominant alleles. The three most common alleles are the ...
Identification of the heterozygous state for the alpha-1-antitrypsin deficiency gene in man. Alpha 1 -antitrypsin (α 1 -at) of individuals homozygous for a gene determining low serum concentrations of this protein can be distinguished electrophoretically from α 1 -at of homozygotes for the more...
