[Problems with clinical application of non-invasive prenatal testing]

Area of Science:

• Genetics
• Molecular Biology
• Obstetrics

Background:

• High-throughput sequencing has propelled non-invasive prenatal testing (NIPT) to become a primary screening tool for fetal chromosomal aneuploidies.
• Advancements in sequencing depth and bioinformatics enable NIPT for detecting chromosomal copy number variations and single gene disorders.

Purpose of the Study:

• To review the current applications and challenges of NIPT.
• To discuss the potential of NIPT in detecting copy number variations and single gene diseases.
• To address issues like public understanding, test accuracy, and optimal subject/gestational age selection.

Main Methods:

• Literature review of NIPT technology and its applications.
• Analysis of current challenges and limitations in NIPT implementation.
• Exploration of emerging NIPT capabilities.

Main Results:

• NIPT is a widely adopted first-line test for fetal aneuploidy screening.
• Potential exists for NIPT to detect copy number variations and single gene diseases.
• Key challenges include public awareness, false results, and appropriate patient/timing selection.

Conclusions:

• NIPT is a rapidly evolving technology with expanding applications beyond aneuploidy screening.
• Addressing current limitations is crucial for optimizing NIPT's clinical utility and patient care.
• Further research is needed to fully realize NIPT's potential for comprehensive fetal genetic analysis.
