Genomic genetics


Last years’ research has shown that deciphering the genome was not the last step in the way. There is an estimation of about 20,000-24,000 human protein-coding genes, but several other points are raising importance: interactions in the genome (ncRNA, miRNA…), dynamic changes in DNA, methylation, interactions with the environment (intra- and extracellular, intra- and extra-organism). All these elements are studied by Genomics, which cannot be separated from Genetics anymore.

The Genetics-Genomics Facility at Biocruces Bizkaia Institute was thus created not only to study previous well-known genetic techniques (search for new genes or markers, mutation testing in patients, verification of new findings), but also, and in an important way as it is part of a Research Institute, to support innovating research in Genomics and its derivative Sciences: Epigenetics, Pharmacogenetics and all their applicability.

Facility management

The science of genetics has contributed decisively to the advancement of health sciences, especially since the decipherment of the Genome in 2000.

Applications to diagnosis and prevention are increasing significantly in medicine and public health, and the number of available genetic tests is growing exponentially. It is estimated that more than 100,000 people in the Basque Country may suffer or suffer from a genetic-based disease or are carriers of it.

With the existing screening and prevention programs, more and more Basque citizens have to make decisions that significantly affect themselves, their reproductive future and their family.
