Biochemical and molecular genetics of cystic fibrosis

Cystic fibrosis (CF) is the most common severe recessive genetic disorder in the Caucasian population. In 1938, D. H. Anderson provided the first comprehensive description of the disease and also introduced the name “cystic fibrosis of the pancreas.” Patients with CF suffer from excessive mucus accumulation resulting in severe clinical consequences in the respiratory, gastrointestinal, and genitourinary tracts (see Table I). All these symptoms are consistent with defects of exocrine glands, as suggested by S. Farber in 1945; he called the disease “mucoviscidosis,” a name still popular in some parts of continental Europe. CF patients also have elevated electrolyte levels in their sweat, an observation which, first described by di Sant’Agnese et al. (1953), became the hallmark for CF diagnosis.link_to_subscribed_fulltex
