Successful pregnancy after preimplantation genetic diagnosis in a female with Robertsonian translocation.
Preimplantation genetic diagnosis (PGD) is an alternative option for couples with chromosome abnormalities. A 34-year-old woman with balanced Robertsonian translocation [(45, XX, der(13; 14)(q10; q10)] requested PGD due to recurrent spontaneous abortion. Embryos of good quality were biopsied on day 3 post-oocyte retrieval. The aspirated blastomeres were fixed and analyzed using fluorescence in situ hybridization. In the first cycle, 2 unaffected embryos were transferred back without success. No unaffected embryo was available in the second cycle. On day 5 in the third cycle, 2 unaffected embryos were transferred resulting in a twin pregnancy. Amniocentesis confirmed the diagnosis. At the gestational age of 35 weeks, 2 healthy girls were born via cesarean section. Postnatal physical examination found no evidence of major abnormalities.
