Question

A)In 1% of cases, COPD is caused by a genetic deficiency in alpha-1 antitrypsin, which is necessary for normal lung development and function. A defect in the CFTR gene causes cystic fibrosis. A mutation in the superoxide dismutase 1 gene causes amyotrophic lateral sclerosis (ALS), a neuromuscular disease that can reduce an individual's ability to control breathing muscles. Certain mutations in the human leukocyte antigen (HLA)allele are associated with increased risk of sarcoidosis, which causes inflammatory cells to collect in the lungs.
