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.

Ethnic Background Detection Rate Carrier Risk Carrier Risk after negative CF screen
African-American 66% 1 in 61 1 in 177
Asian American 55% 1 in 94 1 in 208
Caucasian 89% 1 in 25 1 in 219
Hispanic 74% 1 in 58 1 in 220
Ashkenazi Jewish 94% 1 in 24 1 in 384
