Understanding how CFTR mutations influence disease prognosis
The CFTR mutation is quite common in the general population, with millions of asymptomatic carriers estimated in Europe and the United States. Nevertheless, as two mutant copies (or alleles) of the CFTR gene are required for the clinical manifestation of CF, the actual disease prevalence is significantly less than the carrier frequency.1 An individual with CF can carry an identical CFTR mutation on either allele, or two different CFTR mutations — one on each allele. Depending on the type of mutation, the effect on disease severity and prognosis can be quite different.1-3
