Some people remain healthy for years but then as adults develop breathing difficulties due to emphysema. Alpha1 antitrypsin deficiency-related (AAT) emphysema is caused by the inherited deficiency of a protein called alpha1-antitrypsin (AAT) or alpha1-protease inhibitor. AAT, produced by the liver, is a "lung protector." In the absence of AAT, emphysema is almost inevitable. It is responsible for 5% or less of the emphysema in the United States.Symptoms of AAT deficiency emphysema usually begin between 32 and 41 years of age and include shortness of breath and decreased exercise capacity. Smoking significantly increases the severity of emphysema in AAT-deficient individuals.
