Cystic Fibrosis Carrier Screening Panel

The Cystic Fibrosis Carrier Screening Panel consists of the 41 most common cystic fibrosis (CF) mutations which includes the 23 mutations recommended by the American College of Medical Genetics (ACMG). A negative CF carrier screen significantly reduces but does not eliminate the carrier risk regardless of the number of mutations screened. The detection rate is dependent on the patient’s ethnic background.
