Molecular and functional genomics group (V. Rovīte lab)

The activities of our emerging research group are aimed to discover molecular markers and mechanisms of human disease development and progression to discover potentially actionable targets to improve diagnostics, prognostics and disease management. The studies conducted by our group are fully exploiting close connection to the Latvian national biobank – Genome Database of Latvian population (LGDB), Genome Centre sequencing unit and connection to largest hospitals and medical institutions that enable us to carry out a full cycle of research from patient-derived sample collection to omics analysis, functional studies and final data interpretation. The main projects in our group are related to research of neuroendocrine tumous and autoimmune disease to investigate the development mechanisms of these disease and to find prognostic factors that could help to improve treatment and management. Furthermore, a wide collaborative network in the field of medicine has prompted several collaboration projects in research areas of endocrinology and gastroenterology. Currently, our team is developing novel NGS approaches and building experience in functional studies to retain flexibility and openness to perform state-of-the-art research in the field of translational medicine.
