Alpha-1-antitrypsin deficiency is associated with variable development of airflow obstruction and emphysema. Index patients have greater airflow obstruction than subjects detected by screening, but it is unclear if this reflects smoking differences and/or ascertainment bias, or is due to additional genetic factors. In this study 72 sibling pairs with alpha-1-antitrypsin deficiency were compared using lung...
