Abstract

Cystic fibrosis is the most common autosomal recessive disease in Caucasian populations and has a carrier frequency of 1 in 25 (1 ). The gene involved codes for the cystic fibrosis transmembrane conductance regulator (CFTR), a membrane-associated protein involved in ion transport across the plasma membrane of epithelial cells. To date more than 1000 mutations have been described in this gene, and most are rare (2 ). By focusing on five common mutations it is possible to detect the disease causing mutation in 90% of patients (3 )
