Abstract
Objectives: With the advancement of next-generation sequencing (NGS), whole-exome sequencing (WES) has proven useful in diagnosing various diseases, particularly neurodevelopmental disorders, during both the prenatal and postnatal periods. In this study, we examined the correlation between the results of chromosomal microarray analysis (CMA) and WES in pregnant women, as compared to conventional karyotype analysis and ultrasound (US) findings.
Methods: Fetal US were performed on pregnant females referred to our clinic with suspected fetal anomalies, as well as those who had anomalies detected by targeted US. Comprehensive counseling was provided to all parents. Karyotyping, CMA, and WES were offered for all fetuses through amniocentesis, CVS, and cordocentesis. We compared the demographic data and ultrasound findings of pregnant females with normal and abnormal WES results.
Results: WES results indicated a normal karyotype in 14 pregnant females and an abnormal karyotype in 12 pregnant females. CMA showed an abnormal karyotype in three of the pregnant females, whose WES results were normal. US findings were more frequently observed in pregnant females with abnormal WES results.
Conclusions: Among the organ systems, the cardiac system is at the highest risk for anomalies. The risk further increases when multiple system anomalies are present. Incorporating WES alongside CMA may enhance diagnostic accuracy and be beneficial for subsequent pregnancies. Our US results do not align with the existing literature, and further evaluations with larger patient populations are needed to reconcile these findings with current research.
期刊介绍:
Case Reports in Perinatal Medicine is a double-blind peer-reviewed journal. The objective of the new journal is very similar to that of JPM. In addition to evidence-based studies, practitioners in clinical practice esteem especially exemplary reports of cases that reveal specific manifestations of diseases, its progress or its treatment. We consider case reports and series to be brief reports describing an isolated clinical case or a small number of cases. They may describe new or uncommon diagnoses, unusual outcomes or prognosis, new or infrequently used therapies and side effects of therapy not usually discovered in clinical trials. They represent the basic concept of experiences for studies on representative groups for further evidence-based research. The potential roles of case reports and case series are: Recognition and description of new diseases Detection of drug side effects (adverse or beneficial) Study of mechanisms of disease Medical education and audit Recognition of rare manifestations of disease.
