Cystic Fibrosis (CF) is an autosomal recessive disease in which more than 2000 relevant mutations involving the gene coding for cystic fibrosis transmembrane conductance regulator (CFTR) were identified on chromosome 7 q31.2, and they are categorized in 6 classes according to their impact on the synthesis (class 1), processing (class Il), gating (class III), conductance (class IV), quantity (class V), and recycling (class VI) (1). Here, CFTR is linked to cystic fibrosis.
