Is Cystic Fibrosis an Inherited Disease?

Q:
Is cystic fibrosis an inherited disease?

A:
Cystic fibrosis is caused by a mutation in a gene. The gene called cystic fibrosis transmembrane conductance regulator (CFTR) gene. It changes a protein that is responsible for the movement of salt into and out of cells. As a result, the mucus in the body becomes thick and sticky, and the salt in sweat is increased.

Cystic fibrosis is inherited, and you may get cystic fibrosis or become a carrier if your parents have cystic fibrosis, or they are cystic fibrosis carriers.
