Non-invasive prenatal testing (NIPT) using cell-free fetal DNA from the peripheral blood of the pregnant woman has become a possibility within recent years, but is not yet implemented in Denmark. NIPT has proven to be very efficient in the screening for especially trisomi 21. This article summarizes the basics behinds the most used NIPT techniques and describes which genetic conditions this method may detect. Finally, the future aspects of implementing NIPT in the prenatal screening programme in Denmark are discussed.

Hepatitis and human immunodeficiency virus (HIV) are major public health issues in developing countries, including Ethiopia. These viruses can be transmitted from mother to child during birth or through contact with contaminated blood. In many areas of Ethiopia, viral hepatitis and HIV infections are significant health concerns for pregnant women.

Purpose: We sought to evaluate outcomes for clinical management after a genetic diagnosis from the Deciphering Developmental Disorders study.
Methods: Individuals in the Deciphering Developmental Disorders study who had a pathogenic/likely pathogenic genotype in the DECIPHER database were selected for inclusion ( = 5010). Clinical notes from regional clinical genetics services notes were reviewed to assess predefined clinical outcomes relating to interventions, prenatal choices, and information provision.

The number of human disease genes has dramatically increased over the past decade, largely fueled by ongoing advances in sequencing technologies. In parallel, the number of available clinical genetic tests has also increased, including the utilization of exome sequencing for undiagnosed diseases. Although most clinical sequencing tests have been centered on enrichment-based multigene panels and exome sequencing, the continued improvements in performance and throughput of genome sequencing suggest that this technology is emerging as a potential platform for routine clinical genetic testing.

Purpose: Current literature reports strong support among parents for genetic testing for ill neonates; yet, some parents decline this testing for unknown reasons. We aimed to document the proportion of parents who decline, describe their clinical and demographic characteristics, and categorize their rationales.
Methods: We reviewed medical records to collect and compare clinical and demographic information for patients whose parents consented to and declined recommended genetic testing.

Purpose: Our primary objective was to characterize clinical and procedural factors affecting sample size in chorionic villus sampling (CVS).
Methods: This retrospective, single-site cohort study included singleton pregnancies undergoing transabdominal (TA) and transcervical (TC) CVS between 2020 and 2023. Prenatal and maternal data were obtained from the electronic medical record.
