Yes: There are a number of mutations in the cftr gene on chromosome 7 that can be associated with cf. Even getting more than one from the mother is not associated with disease as long as the cftr gene from the father is normal.
Dr. Amrita Dosanjh
Pediatrics and Pediatric Pulmonology 37 years experience
CF: Cystic fibrosis is an inherited genetic disease. One gene with a CF mutation is inherited from each parent. Parents are either carriers or have the disease itself. Since there are many mutations that can cause cf, the clinical symptoms vary considerably. Initially, infants and children may have no symptoms. The cff.Org or prmg respiratory practice (fax 858 259 9689) for further information.
