Alpha1-antitrypsin deficiency: New therapies on the horizon.

Abstract excerpt

Alpha1-antitrypsin deficiency (AATD) is caused by mutations in the SERPINA1 gene, coding for alpha1-antitrypsin (AAT). AAT is synthesised mainly in the liver and is released into bloodstream to protect tissues (particularly lung) with its antiprotease activity. The homozygous Pi∗Z mutation (Pi∗ZZ genotype) is the predominant cause of severe AATD. It interferes with AAT secretion thereby leading to AAT...
