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

QYQiuxia Yu JGJia-Chun Guo YZYong‐Ling Zhang

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

Abstract

Although monogenic causes were identified in only a small subset of LR defective fetuses, the identification of this condition in the prenatal setting warrants comprehensive fetal anatomic evaluation and invasive genetic testing.
