Cystic fibrosis is a single gene, autosomal recessive disorder, in which more than 1,900 mutations grouped into 6 classes have been described. It is an example a disease that could be well placed to benefit from personalised medicine. There are currently 2 very different approaches that aim to correct the basic defect: gene therapy, aimed at correcting the genetic alteration, and therapy aimed at correcting the defect in the CFTR protein. ⋯ In the last 5 years, CFTR has been designated as a therapeutic target. Ivacaftor is the first drug to treat the basic defect in cystic fibrosis, but only provides a response in a small number of patients. New drugs capable of restoring the CFTR protein damaged by the most common mutations are required.
