From the moment embryo transfer takes place up until the day when a woman takes a pregnancy test, a set of events aimed at achieving implantation (adherence of the embryo to the uterus) take place in the uterus and embryo. The process has traditionally been described as a dialogue and this is, indeed, a good way of explaining […]
Thanks to the donor DNA storage bank at Instituto Bernabeu, patients who need to make use of donated gametes for their fertility treatment may, at any time, make a request (further to egg donor consent) for necessary genetics studies to be carried out with a view to preventing and adequately treating any conditions that may affect their children […]
What are genetics and epigenetics?
Genetics and epigenetics are two, closely-related branches of biology. The former is much more well known and consists of studying how hereditary characteristics are passed on from generation to generation. DNA is the molecule in which genetic information is stored in a 4-letter code: A, C, G and T. The combination of letters is not a matter of chance. On the contrary, they combine in a precise manner because, in living things, the 4 letters make up the code for generating the instructions (genes) for synthesising all proteins. This DNA is in the nucleus of the cells linked to the histones around which DNA wraps itself, as if it were a spool of thread. […]
In the year 2000, human sequencing was achieved following 10 years of scientific work and now, thanks to next generation DNA sequencing, we are able to get to know a human genome in the space of just one week. It is still not possible, however, to access 100% of the genetic information contained within an embryo, the true origin of human life. But scientific progress is unstoppable and with this new technique a new range of promising options for genetics, for fertility and for life have opened up.
According to researchers, the possibilities which DNA sequencing offers are revolutionary and huge. Despite being at a very initial stage in which only the tip of the next generation sequencing iceberg has been uncovered, the number of uses is so varied that determining how to manage everything this technique implies will, in fact, be the future’s biggest challenge.
For the time being, thanks to human sequencing, nowadays “there is greater power of analysis and this facilitates many things and very significant possibilities”, explains the scientist and molecular biology and genetics investigator at Instituto Bernabeu, José Antonio Ortiz. The new technique, which can only be carried out in leading international clinics such as IB, “has revolutionised genetics. Genetic studies are now much quicker.’ […]
