This technique allows a genetic study of an embryo developed by In Vitro reproduction techniques, prior to its transfer. It is mainly used in pairs with:
Cases of repeated abortion with genetic diseases, diagnosed in the embryo.
Previous child with severe genetic condition.
Family history of serious genetic conditions, transmissible to offspring.
A clinical history is made to the couple including a complete genetic evaluation, evaluating in each case the possibility of performing DGPI.
Preimplantation genetic diagnosis looks for genetic and chromosomal problems that place the couple at risk of congenital defects or miscarriage.
MOSTLY COMMONLY ANALYZED DISORDERS
Diseases associated with recessive sex chromosomes, such as hemophilia, fragile X syndrome and neuromuscular dystrophies.
Diseases associated with dominant sex chromosomes such as Rett syndrome, pigmentary incontinence and pseudohyperparathyroidism.
Single gene diseases such as cystic fibrosis, Tay Scachs, Huntington’s disease and sickle cell anemia.
Re chromosomal arrangements such as translocation, inversion, deletions and aneuploidy.
PROCEDURE
Realization of conventional IVF treatment.
Embryonic growth up to 8 cells.
Removal of 1 or 2 embryo cells for study.
Individualized genetic study according to the case.
Transfer of embryos not affected by the genetic condition under consideration.
