Detailed explanation-1: -Mutations in the CFTR gene cause cystic fibrosis. The CFTR gene provides instructions for making a channel that transports negatively charged particles called chloride ions into and out of cells.

Detailed explanation-2: -Cystic fibrosis is caused by mutations in the gene that produces the cystic fibrosis transmembrane conductance regulator (CFTR) protein. In people with CF, mutations in the CFTR gene can disrupt the normal production or functioning of the CFTR protein found in the cells of the lungs and other parts of the body.

Detailed explanation-3: -Cystic fibrosis is caused by mutations, or errors, in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which result in either no CFTR protein being made or a malformed CFTR protein that can’t perform its key function in the cell.

Detailed explanation-4: -Cystic fibrosis is an example of a genetic disease caused by a frameshift mutation. sequence that codes for the 508th. The result in a deletion of the 508th PHE amino acid.

Detailed explanation-5: -Cystic fibrosis (CF) is a genetic disease. This means that CF is inherited. A child will be born with CF only if two CF genes are inherited-one from the mother and one from the father. A person who has only one CF gene is healthy and said to be a “carrier” of the disease.
