Can a Preconception Genetic Screening and Reproductive Risk Assessment Program Reduce Severe Inherited Disease?
Editorial
From the essay
Carrier screening identifies healthy people who carry a gene change that can cause disease in a child. Carriers usually have no symptoms or family history. For many recessive diseases, if both partners carry a disease-causing change in the same gene, each pregnancy has a 25% chance of an affected child. Professional organizations recommend screening before pregnancy, testing the other partner after a carrier result, and genetic counseling. The problem is timing.
