What Role Do Genetic Mutations Play in Prenatal Screening?
Genetic mutations are changes in the DNA sequence that can lead to genetic disorders. Prenatal screening specifically looks for mutations in genes that are known to cause congenital conditions. For instance, mutations in the BRCA1 and BRCA2 genes are screened to assess the risk of breast and ovarian cancers, while mutations in the CFTR gene are checked for cystic fibrosis.
