To our knowledge, this is the first study in less complex patients’ cohorts of monogenic diseases that follows such an integrative approach in rare inherited kidney disease, which are currently not well characterised or understood and for which pharmacological treatments are not curative, leveraging recent technological advances in omics technologies and bioinformatics. The proposed methodology maximises the potential of minimally/ non-invasive biomarker discovery for disease characterisation and elucidation of targets for treatments. The identification of biomarkers that modify the clinical course of prevalent Mendelian nephropathies in Cyprus will inform the design of a novel, robust diagnostic tool targeted to this population and offered in a routine clinical setting. As the prices of genomics and metabolomics analyses drop, such a tool can be easily used in the clinic, replacing expensive tests used today. In turn, this work opens doors for collaboration between industrial and academic parties for the discovery of new druggable targets and the development of novel theranostic tools. This study has a huge potential for better clinical diagnostics, efficient patient stratification and assessment of therapeutic responses. MODIRen can serve as an exemplar for precision nephrology services to the wider population with glomerulopathies, beyond these specific RIKDs. Additionally, the implementation of metabolomics in the realm of biobank.cy’s activities will result in innovative research advancements, in the framework of the first biobank in Cyprus and the study of genetic diseases.
