What this trial studies

This study focuses on improving preimplantation genetic testing (PGT) for couples with genetic diseases by utilizing a new technology called single-tube complete Long fragment whole genome sequencing (stLFR-WGS). The aim is to streamline the testing process for multiple genetic abnormalities while reducing costs and time. By customizing probes and detection methods, the study seeks to enhance the accuracy of genetic testing in embryos, particularly for those with monogenic diseases or chromosomal abnormalities. The study will observe patients undergoing PGT cycles and analyze the effectiveness of this new approach.

Who should consider this trial

Good fit: Ideal candidates for this study are patients undergoing PGT cycles with diagnosed monogenic genetic diseases or balanced chromosomal structural rearrangements.

Not a fit: Patients who have contraindications for PGT or have experienced failures in embryo biopsy or sequencing may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and efficient genetic testing for embryos, improving outcomes for couples facing genetic diseases.

How similar studies have performed: While there have been advancements in genetic testing technologies, this specific approach using stLFR-WGS is relatively novel and has not been extensively tested in similar studies.
