What is cystic fibrosis inheritance pattern?
Cystic fibrosis is an inherited disease. It is caused by a mutation in a gene. The mutated gene 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.
The transmission of cystic fibrosis is related to genetics. If your parents have cystic fibrosis, or they are cystic fibrosis carriers, you may get cystic fibrosis or become a carrier.
You will have cystic fibrosis when you get one copy of the mutated gene from each parent, that means you get two mutated gene in total. However, if you get only one copy of the mutated gene, you won’t get cystic fibrosis and become a cystic fibrosis carrier. And you may pass the gene to your kinds.
