Specific morbidity and mortality rates are unknown. Not all patients with homozygous deficiency develop symptomatic emphysema or cirrhosis; however, among those who develop symptomatic disease, the history of having symptoms for several years and being evaluated by multiple physicians before the diagnosis was made is common. At present, the median time between the observation of symptoms and diagnosis is approximately 8 years. [10] The mortality rate is high in symptomatic patients.
