Evaluation of targeted next-generation sequencing–based preimplantation genetic diagnosis of monogenic disease

A methodology of next-generation sequencing was developed for preimplantation genetic diagnosis and found to be highly consistent with two independent methods of single-gene disorder screening.

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.
