About

The Clinical Genomics Unit (UGC) is part of the Genetics Department at Germans Trias i Pujol University Hospital (HUGTiP) in the North Metropolitan Area of Barcelona (LCMN). The research 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. The group is dedicated to improving patient management by considering all aspects of patient care, including emotional, social, religious, and physical dimensions.

The group is also focused on increasing the cost-effectiveness of genetic testing and enhancing their knowledge of the genetic bases of various diseases, both monogenic and poligenic diseases. To achieve this goal, they are actively developing new genomic techniques to analyze germline and somatic variants at both RNA and DNA levels and implementing a new technology for massive genotyping to stablished new pooligenic risk scores. Additionally, the group is participating in developing new methodologies to determine the status of known pharmacogenomics biomarkers by taking part in PHARMA-IMPCAT and establishing the Pharmacogenomics Unit at HUGTiP.

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 group is working on developing personalised 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.

    Elisabeth Castellanos Pérez

    In 2009 she enrolled at the Germans Trias i Pujol Research Institute (IGTP) to be in charge of the genetic diagnostics activity of the Hereditary Cancer program. Since 2015, she is the coordinator of genetic diagnosis in the Spanish Reference Center (CSUR) on Phakomatoses. In addition, she also participates in the Catalan Health Institute's XIGENICS program, and collaborate closelly with the Institut Català d'Oncologia (ICO), and with Dr Lázaro.

    During 2009-2019, she developed her activity of diagnosis, innovation and research within the Hereditary Cancer Group, led by Dr Serra. In 2019, she moved to the Germans Trias i Pujol Hospital (HUGTP) to coordinate the Clinical Genomics Unit, and was recognised as emerging principal investigator at IGTP. Since then, a translational research activity has been going on centered in CSUR patients aimed to develop and implement new genomic strategies to evaluate genetic individual susceptibility to illness.

An international study validates the efficacy of a drug in adults with neurofibromatosis type 1

An international study, published in The Lancet, demonstrates for the first time that the drug selumetinib is effective in reducing tumours and associated pain in adults with neurofibromatosis type 1 (NF1). IGTP and Hospital played a key role in the clinical trial, which marks a significant advance in the treatment options for this rare genetic disease.

A new cell model to advance research into NF2-related schwannomatosis

A study led by the Clinical Genomics Unit (UGC) has established a new cell model to advance research into NF2-related schwannomatosis (SWN-NF2), a rare genetic disease. The work, published in the journal Genes & Disease, describes the generation and characterisation of cell spheroids derived from induced pluripotent stem cells (iPSC)-a type of stem cell capable of transforming into almost any cell type-that reproduce the alterations observed in tumours associated with the disease.
