title: Genetic analysis of cystic fibrosis in Denmark. Implications for genetic counselling, carrier diagnosis and prenatal diagnosis.
abstract: Cystic fibrosis is the most common, severe, inherited disease in the Caucasian population. As a consequence, the demand for genetic counselling of patients with cystic fibrosis and their families is large. In Denmark the incidence of cystic fibrosis is 1:4700, which is quite low compared to other European countries. We have investigated 268 Danish cystic fibrosis patients with respect to DNA markers (haplotypes) and the most common mutation delta F508. The delta F508 mutation is found on 88% of all cystic fibrosis chromosomes, the highest frequency reported so far. This had had an important impact on genetic counselling, prenatal diagnosis and eventually population screening. In the Danish population 78% of all couples at risk will be informative for delta F508 and will be identifiable by simple screening methods.
