The CF gene codes a molecule that channels salt across…
““The CF gene codes a molecule that channels salt across cellular membranes. The most common mutation is a deletion of three bases of DNA that results in the removal, or deletion, of just one amino acid from the protein (in the language of genes, three bases of DNA encode a single amino acid). This deletion creates a dysfunctional protein that is unable to move chloride-one component of sodium chloride, i.e., common salt-across membranes. The salt in sweat cannot be absorbed back into the body, resulting in the characteristically salty sweat. Nor can the body secrete salt and water into the intestines, resulting in the abdominal symptoms.””
About This Quote
Source Book: The Gene: An Intimate History, 2016
The CF gene mutation removes a single amino acid, disabling chloride transport and causing salty sweat and digestive issues.
In simple terms: A mutation blocks salt movement, leading to salty sweat and gut problems.
