摘要

Cystic fibrosis (CF) is caused by mutations in the ABCC7 gene that encodes the cystic fibrosis transmembrane conductance regulator (CFTR), a cAMP-depen-dent Cl~ channel. The gene consists of 6129 base pairs on chromosome 7, and over 1200 mutations have been identified. In the hepatobiliary system, CFTR, a transmembrane protein, is located on the apical membranes of cholangiocytes and cholecystocytes but not hepatocytes. As there are no reliable serum markers, establishing the true prevalence of hepatobiliary disease in CF is difficu moreover, definitions of clinical liver disease vary. Estimates of the prevalence of liver disease range from 4.2% to 27% depending on age. Liver disease has become the third leading cause of death in CF. The classical hepatic histopathological lesions of CF liver disease are focal biliary fibrosis, multilobular cirrhosis and 'black' pigment gallstones.
