WebCystic fibrosis (CF), first described in 1938, is a common, life-limiting monogenetic disease. The discovery of the cystic fibrosis transmembrane conductance regulator (CFTR) gene in 1989 was crucial in advancing our understanding of disease pathogenesis and paving the road for treatment aimed at the fundamental molecular defect. WebWhen the CFTR protein is made using all of the correct amino acids, it forms a stable 3-D shape. It has to be the right shape to transport chloride. When a mutation causes an amino acid to be deleted or an incorrect amino acid to be added, the CFTR protein cannot form its correct 3-D shape and function properly. These mutations are considered ...
