More than 3 million Spaniards and 29 million Europeans suffer from some of the nearly 8,000 rare diseases that exist. Currently, it is possible to prevent the transmission of many of these diseases, which are characterized by degenerative and risk of life, sometimes at early ages.


Children playing Preimplantation diagnosis

Preimplantation Diagnosis (PGD) is a technique that responds to those suffering inherited diseases and who dread having sick children by high transmission probabilities. An example is Huntington's disease, a progressive degenerative disease caused by alteration of chromosome 4 DNA, and whose symptoms usually appear towards the middle of life. In this case, the descendants of the people affected have a 50% chance of developing the disease.

In Assisted Reproduction , through techniques such as PGD can detect embryos affected by the disease, so that only the mother transferred to those who are healthy.


Spontaneous abortions

The PGD method is applied in one of the few centers nationwide, Zygos, technique is also effective in cases of abortions "repeat". This situation occurs when a woman has had two or more abortions, whose reasons are ignored, or if they have knowledge that a parent has an altered karyotype. This is a distressing situation as the woman gets pregnant, but keep in mind the possibility of miscarriage.


DGP to ensure pregnancy

There are couples who have a healthy son and several abortions. In these cases you should also advise the DGP. There are a variety of family situations in which this technique solves the problems of sterility or abortions, as in those in which women have managed to have a healthy child, but after suffering abortions. It may be that a first child by natural methods have, but in the second difficulty conceiving arise.
