Q 
A boy had a mutation in the CFTR gene, resulting in abnormal chloride conductance on the apical membrane of the epithelial cell. This defection ion transport leads to defective mucociliary clearance, causing mucus obstruction. After several years, he has acquired numerous bacterial infections and has clogged airways due to the thick mucus. He had to go on treatment. The above scenario is an example of which concept?
A. Pathogenesis
B. Genetic derangement
C. Complications
D. Etiology
A
