Diane van Opstal

Diane van Opstal is a Researcher in the Department of Clinical Genetics at Erasmus MC, Erasmus University Rotterdam, specializing in prenatal genetic diagnostics and cytogenetic analysis. Her work bridges clinical practice and genomic research with a focus on improving non-invasive screening methodologies.

Her primary research domains include:

• Mosaicism (particularly confined placental mosaicism)
• Cell-Free DNA analysis for prenatal screening
• Cytogenetic techniques including karyotyping and exome sequencing
• Chromosomal aberrations in fetal development
• Blastocyst genetics and retrospective cohort studies

Recent publications reveal a concentrated effort in optimizing non-invasive prenatal testing (NIPT) protocols, with critical investigations into chorionic villus sampling confirmation for high-risk trisomy cases, mosaic ratio correlations with pregnancy outcomes, and exome sequencing applications for congenital anomalies. Her collaborative studies frequently address diagnostic pitfalls in dystrophinopathies and placental mosaicism, directly impacting clinical guidelines in European prenatal care.

Van Opstal actively contributes to high-impact journals including Prenatal Diagnosis and the European Journal of Human Genetics, where her commentaries shape discourse on genetic counseling standards and diagnostic accuracy. Her research consistently emphasizes translational applications, converting genomic findings into actionable clinical protocols for improved patient management in high-risk pregnancies.
