Urko M. Marigorta (Martinez Marigorta) is a Ikerbasque Research Fellow and La Caixa Incoming Junior Leader working in the Bioinformatics Unit of the CIC bioGUNE since October 2018. His research interest lies in devising new methods for assessment of genetic risk of disease, and gearing genetic knowledge towards implementation of precision medicine based solutions in the clinical practice. He has expertise in several disciplines related to disease genomics, including bioinformatics, genetic epidemiology, statistical genomics, and evolutionary and quantitative genetics.

Dr. Marigorta carried out his PhD at the Universitat Pompeu Fabra in the PRBB in Barcelona. Under the supervision of Prof. Arcadi Navarro, his thesis focused on comparing the genetic architecture of complex disease across human populations. His work supported the infinitesimal model of genetic risk to a greater extent than previously appreciated and confirmed that prediction of genetic risk should be transportable across ethnicities (Marigorta et al., PLoS Genetics, 2013). In 2013 he moved to the United States to carry out a postdoc at the Georgia Institute of Technology in Atlanta. Under the mentorship of Prof. Greg Gibson, during the last five years Dr. Marigorta enhanced his knowledge bases in functional and integrative genomics, making important conceptual and analytical contributions. The two highlights of his postdoc are the work as main RNA-Seq analyst in the RISK team that build a new model to predict risk of complications in pediatric Crohn’s disease (Kugathasan et al., The Lancet, 2017) and devising the transcriptional risk scores to predict risk of disease (Marigorta et al., Nature Genetics, 2017).

The main research interest of the Marigorta lab revolves around the genetic basis of disease in humans. We identify emerging questions about complex disease etiology, and tackle them using an integrative approach at the interface of statistical, quantitative and evolutionary genomics. Through collaboration with doctors working in the clinic, we analyze data from –omics profiling of patient cohorts to illuminate our understanding of disease pathogenesis and, eventually, gear this knowledge towards translational advances. The long-term goal of this research lies in achieving precision medicine: being able to use individual profiles to personalize health treatment, ensuring that the right medications are used for the right patients, and tailoring medical care to patient needs.

At present, our work focuses on combining statistical genomics and medical transcriptomics (gene expression) to improve our ability to estimate risk of disease and predict phenotypes. These are the three main lines of research in the lab:

1. Statistical genetics for understanding susceptibility to disease
Whereas the last years in human genetics have been mostly about discovering loci associated with disease, the field is now shifting towards interrogation of cells and tissues from patients to characterize the molecular underpinnings of disease. As a biomarker that integrates genetic and environmental risk, we analyze transcriptomic data to uncover genetic regulatory programs that modulate risk of disease. We pay special attention to discovering genetic variants that are activated to engage in protective responses that decrease risk, as they can be the key to understand why most individuals do not develop disease. Although our work is currently focused on autoimmune disease, especially inflammatory bowel disease, we are happy to collaborate with researchers working on other disease classes.

2. Individual prediction of disease risk
A central goal of personalized medicine is to deliver numerical scores that can assess risk of disease and predict response to drug therapy for each individual. In the last few years a flurry of papers has demonstrated that polygenic risk scores can be used for stratification, pinpointing at subgroups of individuals with significantly enhanced risk of disease. Yet, estimating disease risk is only the first step in the quest for incorporating genomic information into standard clinical practice. We are currently addressing two of the main incoming challenges in this area, namely devising new methods for adapting genetic risk estimates according to information about environmental and lifestyle factors, and transforming them into tools that can be routinely used as biomarkers by doctors. In particular, a central focus is adapting the transcriptional risk score methodology to disease classes other than autoimmune disease and to tissues with easier access such as peripheral blood.

3. Heterogeneity and interactions in disease
We are interested in understanding the role that our current western lifestyle, and particularly its imbalance with human evolutionary history, plays in the heritability and genetic susceptibility of modern diseases such as type 2 diabetes and other anthropometric traits such as body mass index. Taking profit of the availability of large datasets such as the UK Biobank, we are currently working on new statistical methods to detect non-additive effects, such as epistatic and gene-by-environment interactions, that shape genetic susceptibility to disease.

In summary, our research strengthens the genomics and bioinformatics research portfolio at the CIC bioGUNE and adds an integrative –omics perspective aimed at helping towards successful implementation of precision medicine based solutions in the Basque Country.
