Genetic profiling enhances cystic fibrosis prenatal diagnosis.

Prenatal testing is a standard approach for detecting genetic diseases in expectant mothers, with more testing options becoming available. Homozygosity mapping is invaluable for identifying genes causing disease and improving molecular diagnostics. Here, we present the prenatal diagnosis outcomes of three families affected by cystic fibrosis (CF). A combination of phenotypic analysis, haplotype analysis, and CFTR gene sequencing was used to identify the causative mutations. This allowed for the effective detection of individuals misdiagnosed with routine screening procedures. A method that is potentially useful for similar autosomal recessive disorders. Our findings indicate that enhanced diagnostic accuracy enables earlier clinical interventions that lead to better management of affected pregnancies and improved neonatal care. We show the significance of comprehensive genetic testing to boost diagnostic accuracy for recessive diseases and minimize the risk of diagnostic errors in prenatal settings.
