About

The Clinical Genomics research group is part of the Genetics Department at Germans Trias Hospital in the North Metropolitan Area of Barcelona (LCMN). The group has several important responsibilities, including diagnosing and monitoring patients with hereditary diseases, providing genetic counseling to patients and their families, and conducting genetic tests to determine the genetic cause of these diseases. This research group is dedicated to improving patient management by considering all aspects of patient care, including emotional, social, religious, and physical dimensions.

Their members are also focused on increasing the cost-effectiveness of genetic testing and enhancing their knowledge of the genetic bases of various diseases. To achieve this goal, they are actively developing new genomic techniques to analyze germline and somatic variants at both RNA and DNA levels. Additionally, they are participating in the development of new methodologies to determine the status of known pharmacogenomics biomarkers and to detect SARS-COV-2.

Furthermore, the group is a member of the Spanish Reference Center (CSUR) for adult patients with Phakomatoses (Neurofibromatoses, Schwannomatosis, Tuberous Sclerosis, and Von-Hippel Lindau diseases), which is a part of the European Network of Reference Centers (ERN) GENTURIS. The team is working on developing personalized medicine for this group of patients and developing new clinical guidelines that also take into account patients' emotional and social needs. They are also discovering new prognostic biomarkers, understanding the role of genomic alterations in the development of disease-associated lesions, and implementing various gene therapy strategies to cure these diseases.

Clinical Genomics Research

Research lines

Management of phakomatoses patients

Improving the management of phakomatoses patients considering not only clinical diagnosis but also emotional, social, religious and physical dimensions that could impact patients with these rare diseases.

Development and implementation of new genomic techniques for genetic diagnosis of hereditary diseases

Increasing the cost-effectiveness of genetic testing and our knowledge of the genetic basis of some hereditary diseases (mostly phakomatoses and hereditary renal diseases). The group is focusing research on developing new genomic techniques, both at RNA and DNA levels, to analyse both germline and somatic variants.

Personalised medicine for neurofibromatoses

Developing personalised medicine for neurofibromatoses and schwannomatosis patients, which include the discovery of new prognostic biomarkers, understanding the role of patient's genomic alterations in the development of disease-associated lesions and the implementation of different gene therapy strategies as a potential treatment for this group of diseases.

Genetic susceptibility to illness

Developing strategies to evaluate genetic individual susceptibility to illness. This will allow for the implementation of personalised and precision medicine in different areas of the Can Ruti campus.
