Cystic fibrosis (CF) is the most common recessive lethal genetic disorder, particularly affecting Caucasians of Northern European descent, with an incidence of approximately 1 in 3,300 births and a carrier rate of 1 in 29. Detection of a variant in one exon is useful in patients with a known familial variant that is not included in the general cystic fibrosis mutation panel.
