Can you get cystic fibrosis without family history?

Cystic fibrois is caused by an altered gene that a person inherits from his or her parents. CF is inherited in a recessive manner, which means both parents must be carriers to have an affected child. A person who has no family history of CF and no children with CF can still be a CF carrier.
