Each type 1 collagen molecule contains three subunits, two are identical (the alpha 1 chains) and the sequence of the third (alpha 2) is very similar. They are encoded at the non-synthenic loci, COL1A1 and COL1A2 and restriction site dimorphisms have been described at each locus. ...
Alpha-1 antitrypsin deficiency (AATD) is a genetic disorder caused by mutations in the 伪-1 antitrypsin gene that can affect both lung and liver. The clinical management of individuals with AATD is complicated by the multitude of different genotypes that confer varying odds for both organs. The...
Those that consented to the study were subjected to a standardized questionnaire and have their Alpha-1-Antitrypsin level and genotype determined by the AlphaKit.Eleven patients, between the ages of 14 - 17 with a mean age of 16, participated in the study. They were all tall and thin and ...
Alpha-1 antitrypsin (AAT) is a protein produced in liver cells that protects lung tissue from damage caused by certain enzymes.8In AATD, a mutation in the SERPINA1 gene can lead to liver disease independently or in combination with lung disease.9People with the Pi*ZZ genotype have the highes...

Alpha1-antitrypsin (α1AT) is an abundant serine-protease inhibitor in circulation. It has an important role in neutralizing the neutrophil elastase activity. Different pathogenic point mutations like Z(E342K)-α1AT have been implicated in the devel
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...
