Preimplantation genetic testing for X-linked chronic granulomatous disease induced by a CYBB gene variant: A case report.

ABSTRACT:

Introduction

X-linked recessive chronic granulomatous disease (XR-CGD) is a severe primary immunodeficiency principally caused by a CYBB (OMIM: 300481) gene variant. Recurrent fatal bacterial or fungal infections are the main clinical manifestations of XR-CGD.

Patient concerns

In the current case, in vitro fertilization (IVF) associated with preimplantation genetic testing for monogenic disorder (PGT-M) was applied for a Chinese couple who had given birth to a boy with XR-CGD.

Diagnosis

Next-generation sequencing-based SNP haplotyping and Sanger-sequencing were used to detect the CYBB gene variant (c.804 + 2T>C, splicing) in this family.

Interventions

The patient was treated with IVF and PGT-M successively.

Outcomes

In this IVF cycle, 7 embryos were obta
