Genomic analysis has provided research opportunities, new approaches to therapeutic development, health care and public health management. These advances allows the assessment of the predisposition to certain diseases which implies more informed clinical management and lifestyle changes.
Understanding genetic predisposition to disease and knowledge of lifestyle modifications that change the potential for a disease is necessary to make informed choices. This multidisciplinary line promotes and disseminates fundamental, translational and clinical scientific research having as main vectors the interaction environment-genome in developmental disorders, aging-related chronic diseases, and cancer.
We aim to understand the impact of genetic/epigenetic factors and environmental/microenvironment exposures on health and on the susceptibility and course of disease. An important focus is to study genotypes, transcripts, methylation markers, proteins and metabolites together with environmental risk factors and clinical information as powerful tools to understand the human variability and networks underlying diseases. This multidisciplinary approach includes study of human genome variability, identification of new biomarkers, essential for disease risk and outcome prediction, and to identify new therapeutic targets translating into clinical research.
Main achievements in the last 5 years:
1) Understand the role of genomic CNVs in various neurodevelopmental disorders that lead to cognitive impairment, improving patients’ diagnosis and therapeutic interventions. We proposed a classification that contributes to the genotype/phenotype correlation, with the delineation of laboratory criteria which help to classify the various CNVs detected, clustering our findings of 1000 patients with developmental delay into 5 classes. Genetic characterization of human iPSC lines, namely from a patient with laterality defects and associated congenital heart anomalies carrying a DAND5 missense alteration.
2) Analyze the impact of fetal chromosomal disorders on maternal blood metabolome, exploring new putative biomarkers and demonstrating the potential of plasma metabolomics. We participated in the assessment of the urinary metabolite signature of prematurity in newborns.
3) Identification of single nucleotide polymorphisms (SNPs), and epigenetic abnormalities that may affect the risk of disease development and may constitute novel genetic risk markers for neoplasia’s susceptibility, providing new therapeutic targets. We showed that chromosomal rearrangements, ex i(17q), and CNVs are related with Chronic Lymphoblastic leukemia.
4) Identification of genomic and epigenetic signatures with capability to predict recurrences and/or metastasis in the head and neck cancer; establish patients' prognosis and survival and also correlated to different clinical-pathological features, such as anatomic site, tumor stage and risk factors;
5) Identification of new prognostic biomarkers with capability to help in the early detection, diagnosis and ultimately in the development of new therapeutic strategies for head and neck cancer.
