Abstract
Objective:
To investigate the applicability of next-generation sequencing (NGS) to preimplantation genetic diagnosis (PGD), this study aims to evaluate semiconductor-based NGS for genetic analysis of human embryos.
Design:
Blinded.
Setting:
Academic center for reproductive medicine.
Patient(s):
Six couples at risk of transmitting single gene disorders to their offspring.
Intervention(s):
None.
Main Outcome Measure(s):
Embryonic genotype consistency of NGS with 2 independent conventional methods of PGD.
Result(s):
NGS provided 100% equivalent PGD diagnoses of compound point mutations, and small deletions and insertions when compared to both a reference laboratory and internally developed qPCR based analyses. Furthermore, NGS single gene disorder screening could be performed in parallel with qPCR based comprehensive chromosome screening.
Conclusion(s):
NGS can provide blastocyst PGD results with a high level of consistency to established methodologies. This study and its design could serve as a model for further development of this unequivocally important and emerging technology.
