Alpha-1-antitrypsin deficiency: An overview of recent advances
Alpha 1-antitrypsin (αl AT), a serpine, is one of the most important proteinase inhibitor in the serum and plays an essential role in protection of the lung tissues against the proteolytic attach of elastase. The gene for a1AT is located on chromosome 14 q 32 and is highly susceptible to mu...
