Genetic Investigation of Fetal Left‐Right Laterality Defects Identified in the Second Trimester of Pregnancy

Key Points

• This research aims to investigate genetic causes of fetal left-right laterality defects identified during pregnancy.
• Examined monogenic causes of left-right laterality defects
• Conducted prenatal evaluations
• Utilized invasive genetic testing for thorough assessment
• Monogenic causes identified in a small subset of defective fetuses
• Emphasized the importance of comprehensive fetal evaluations
• Highlighted the necessity for invasive genetic testing in prenatal care
