title: Carrier screening for cystic fibrosis.
abstract: Cystic fibrosis is the first genetic disorder for which universal screening of preconceptional or prenatal patients became a component of standard prenatal care. The molecular genetics and mutation profile of the CFTR gene are complex, with a wide range of phenotypic consequences. Carrier screening can facilitate risk assessment for prospective parents to have an affected offspring, although there remains a small residual risk for carrying a mutation even with a negative screening result. There are ethnic differences with respect to disease incidence and effectiveness of carrier testing, which may complicate counseling.
