Summary
Population screening for cystic fibrosis (CF) heterozygotes shows that offering genetic testing via personal invitations improves acceptance. Couple screening during pregnancy is efficient and consumer-friendly for routine healthcare integration.
Area of Science:
- Medical Genetics
- Genetic Screening
- Public Health
Background:
- The cystic fibrosis (CF) gene was cloned 7 years ago, prompting numerous population screening trials for CF heterozygotes.
- Screening acceptance rates vary significantly based on the method of offer, with personal invitations yielding higher engagement than mail or leaflets.
Purpose of the Study:
- To evaluate the effectiveness of different approaches for population screening of cystic fibrosis heterozygotes.
- To compare sequential and couple screening models for CF carrier screening during pregnancy.
Main Methods:
- Analysis of experimental trials involving population screening for CF heterozygotes.
- Comparison of two screening models during pregnancy: sequential screening and couple screening.
- Assessment of acceptance rates based on the method of offering screening (personal invitation vs. mail/leaflet).
Main Results:
- Personal invitations significantly increase acceptance rates for CF heterozygote screening in young adults.
- Screening during pregnancy has shown more satisfactory results compared to other age groups.
- Couple screening is efficient, trouble-free, and consumer-friendly, reporting "high risk" only when both partners are positive.
Conclusions:
- The method of offering screening is crucial for acceptance rates in population-based genetic testing.
- Couple screening during pregnancy is a preferred model for cystic fibrosis carrier detection due to its efficiency and user-friendliness.
- Couple screening is recommended for integration into routine healthcare for CF carrier identification.

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
