CF Genetics

Cystic fibrosis (CF) is a genetic disease. This means that people inherit it or get it from their parents through genes. Genes also decide a lot of other body characteristics, including height, hair color and eye color.

If you or your child has recently been diagnosed with CF, you may find the information about the disease confusing and overwhelming at first. This is normal.

This section aims to give you an overview of the genetics related to CF, how it is passed to children and more. If you have more questions, speak with your CF doctor or a genetic counselor at your CF care center.

In this Section: 

  • CF Genetics Basics — An overview of the genetics of CF and how it is inherited.

  • Carrier Testing for CF — Frequently asked questions about tests to find out if a person carries one mutation of the CF gene.

  • CF Mutations — Learn more about specific CF gene mutations in this four-part video series.

  • CF Genetics Webcasts — Watch webcasts and learn more about CF genetics, including CF gene mutations and genetic counseling.

  • CFTR2 — The CFTR2 website contains information about specific cystic fibrosis mutations for people with CF, family members, health care providers and scientists.
