Acid starch gel electrophoresis and two dimensional immuno-electrophoresis have been used to recognize genetic variants of human 伪1-antitrypsin; 9 phenotypes have so far been found. They are inherited by a series of autosomal codominant alleles. One in 750 New Zealanders has a severe serum ...
Alpha-1 antitrypsin deficiency (AATD, OMIM #613490) is a rare metabolic disorder affecting lungs and liver. The purpose of this study is to assess the impact of the US orphan drug act on AATD by providing a quantitative clinical-regulatory insight into the status of FDA orphan drug approval...

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. Other phenotypes associated with alpha1-antitrypsin emphysema and liver disease include ...

Objective Alpha-1 antitrypsin deficiency (AATD) is a common, potentially lethal inborn disorder caused by mutations in alpha-1 antitrypsin (AAT). Homozygosity for the 'Pi*Z' variant of AAT (Pi*ZZ genotype) causes lung and liver disease, whereas heterozygous 'Pi*Z' carriage (Pi*MZ genotype)...
The symptomatic liver disease, however, develops in only 10-15% of children carrying the PiZZ phenotype and not in PiSS, PiNull and PiSZ phenotypes during childhood.The affected children have different degrees of severity of the liver involvement; approximately 25% will develop early cirrhosis ...

Abnormal alpha1-AT phenotypes are associated with an increased prevalence and severity of asthma, suggesting that, under normal circumstances, alpha1-AT modulates the effect of inflammatory mediators involved in the pathogenesis of asthma. The development of asthma in patients with alpha1-ATD may ...
