Cystic Fibrosis Genetics

Wed, 12/30/2015 - 10:40 -- IV Solutions

Cystic Fibrosis (CF) is a genetic disease, an illness someone is born with that is not contagious. Because the problem is in the building blocks that make up a person, most genetic diseases cannot be cured—yet. While we cannot cure cystic fibrosis, IV Solutions helps treat the symptoms. Continue reading to learn about cystic fibrosis genetics, causes, and testing. Please share this article to help build CF Awareness.

Causes of Cystic Fibrosis

In the United States, 1 in 20 people carry an abnormal CF gene. A cystic fibrosis carrier has no related health problems, and probably has no idea they are carriers. When two people with the CF gene have a child, there is a 1 in 4 chance that the child will have cystic fibrosis.

A person born with CF has a protein called the cystic fibrosis transmembrane conductance regulator (CFTR). The CFTR proteins block the usual flow of water and salt in the lungs, pancreas, colon, and genitourinary system. Because the salt and water is blocked, the body produces thicker mucus, which clogs the pathways of the body and leads to the symptoms of cystic fibrosis.

Genetic Testing for Cystic Fibrosis Carriers

One way to prevent the spread of cystic fibrosis is for people to have a blood sample tested for the carrier gene. Usually one partner takes the test—if they are found to have the carrier gene, the other partner can see if they have it, too.

There are over 400 versions of the CF gene, and not all of them can be detected. But current tests are 80–85% accurate and help people decide if they want to conceive a child. Women planning on having a baby should speak to their OB/GYN doctor about cystic fibrosis carrier testing.
