Formerly known as cystic fibrosis of the pancreas, this entity has increasingly been labeled simply cystic fibrosis (https://omim.org/entry/219700). Manifestations relate not only to the disruption of exocrine function of the pancreas but also to intestinal glands (meconium ileus), biliary tree (biliary cirrhosis), bronchial glands (chronic bronchopulmonary infection with emphysema), and sweat glands (high sweat electrolyte with depletion in a hot environment). Infertility occurs in males and females.
For discussion of a phenotype consisting of bronchiectasis with or without elevated sweat chloride caused by mutation in the genes encoding the 3 subunits of the epithelial sodium channel, see BESC1 (211400).
