Is cystic fibrosis genetic?

Explanation:
Cystic fibrosis is a genetic disorder caused by mutations in the CFTR gene, inherited in an autosomal recessive pattern. This means a person has CF only if they inherit two defective copies, one from each parent, who are usually carriers without symptoms. It is not caused by a viral infection, and it is not contagious—CF cannot be spread from person to person. Antibiotics are used to treat bacterial lung infections and other complications in CF, but they do not cure the disease itself. Genetic testing and counseling can identify carrier status and guide family planning.
