Question

Quizplus · Accepted Answer

The CFTR gene codes for a protein that functions as an ion channel, facilitating the transport of chloride ions across cell membranes. This has a significant impact on the function of multiple organs, including the lungs, pancreas, and digestive system. In individuals with cystic fibrosis, mutations in the CFTR gene lead to the production of a non-functional or reduced-function protein, resulting in impaired ion transport and a range of associated symptoms.
