O fenótipo Pi ZZ está associado com maior frequência à doença pulmonar, sendo responsável pelo aparecimento precoce de enfisema, sobretudo nos fumadores. Os autores apresentam dois casos de diagnóstico tardio e em que estiveram presentes outros factores que terão contribuÃdo para o aparecimento de manifestações clÃnicas.Rev Port Pneumol 2007; XIV (2): 295-302 Abstract: The alpha-1 antitrypsin deficiency is an hereditary autosomic codominant disease. The phenotype Pi ZZ is associated more frequently with pulmonary disease and is responsible for the presence of emphysema early in life, particularly in smokers.
