Fish based preimplantation genetic diagnosis to prevent DiGeorge syndrome.

PURPOSE: To report the performance of fluorescence in-situ hybridization in the setting of preimplantation genetic diagnosis in order to diagnose embryos affected by DiGeorge syndrome.

DESIGN

Case report.

SETTING

Academic referral center.

PATIENT: A 32 year-old female affected by DiGeorge syndrome.

INTERVENTION(S): History and physical examination, karyotyping, amniocentesis, preimplantation genetic diagnosis, fluorescence in-situ hybridization.

MAIN OUTCOME MEASURE(S): Avoidance of pregnancy with embryo affected by DiGeorge syndrome.

RESULT(S): Termination of pregnancy with an affected embryo followed by fluorescence in-situ hybridization based preimplantation genetic diagnosis and delivery of healthy offspring.

CONCLUSION(S): The combination of preimplantation genetic diagnosis with fluorescence in-situ hybridization is recommended to prevent pregnancies with DiGeorge syndrome affected embryos in properly selected patients.
