The first child born without the gene for breast cancer: selected in Spain

Talking about GE brings everything to a human dimension that we thought belonged only to the science fiction film and literature. Yet, Spain is the first child born genetically modified so they do not have the gene for breast cancer. The happy event took place last Christmas, but only now being presented to the world: in practice, this child is the first human being can be defined as "genetically selected" before birth and where you removed the BRCA1 gene - as "gene brother BRCA2 - increases the chances of getting breast cancer, but also in the ovaries and pancreas.

The parents made sure the little daughter's health before birth, but it will be so effective? This decision was taken in such an innovative program of assisted reproduction Puigvert-Sant Pau in Barcelona. In reality, the decision was boosted mainly by the desire to prevent mother to her daughter her own family history, dotted with breast cancer.

The pair then made a request for authorization to the National Commission for Assisted Reproduction, which thus has first given the green light to the use of techniques of pre-implantation genetic diagnosis for cancer. This news adds to the case of the woman who has chosen for the complete removal of the breast to prevent cancer, after which both the mother and sister were hit by the disease.

The special authorization of Spain is not, however, unique in Europe as Great Britain also authorizes this type of work, allowing the birth, in 2009, the first English child without this gene dangerous. For these special cases it seems highly specified genetic selection and should also be encouraged by the doctors themselves: it is not the whims of parents who want to choose the sex of the unborn or the color of his eyes, but a cause that should prevent be considered more often.

From Barcelona to know that they will be assessed in detail individual cases now in the hospital of Sant Pau are awaiting permission to proceed with this same method to another case like this, where there is a family history of colon cancer. In Italy every genetic selection is forbidden, yet every day brings more hope to fight breast cancer taking it to the origin, such as blocking the enzyme that creates metastases.

Science has come up where recently arrived only science fiction: it is not uncommon, in fact, run into a film that speaks of perfectly healthy children for the decision of the genetic parents. Although it may seem contrary to nature, there are many choices when you consider the health of their children: how can one criticize the decision of this couple? So as you can not comment on the mother's eggs frozen for her daughter for two years to ensure the baby, suffering from a genetic disease, the possibility of becoming a mother.

There are delicate decisions that may be ethically questionable, but it should be humanly understood.
