Also called since 1944 mucoviscidosis as the body makes thick and sticky mucus that can cause damage throughout the body, including airways and lungs, cystic fibrosis (CF) is a autosomal recessive condition chiefly affecting Caucasian populations.[1] The disease is caused by mutations in the gene providing instructions for synthesizing the cystic fibrosis transmembrane conductance regulator (CFTR) protein chloride transport channel.[2]. Here, CFTR is linked to cystic fibrosis.
