About Stefano Romeo

Professor, Senior Consultant, Principal Investigator, MD, PhD

Stefano Romeo is Professor in Molecular and Clinical Medicine at the Institute of Medicine at the Sahlgrenska Academy. He earned his Medical Degree at Campus Biomedico University in Rome in 2001, Italy and completed his residency in Endocrinology and Metabolic Disease in 2006 at Sapienza University of Rome. He moved to the Wallenberg Laboratory in 2011 after an Italian PhD fellowship carried out at the University of Texas Southwestern Medical Center (2006-2009), Dallas, USA, and a Clinical Lectureship at the University of Cambridge, UK (2009-2011).

Dr Romeo’s main research focus is the role of genetic variants in modulating serum lipid levels and metabolic liver disease. His research field ranges from genetic association studies in large cohorts to molecular genetics of human mutations.

Since 2014, he has been responsible for the Lipid Clinic at the Department of Cardiology, Sahlgrenska University Hospital. The Lipid Clinic focuses on genetic testing and treatment of severe forms of hypercholesterolemia and hypertriglyceridemia. He is also a Faculty Member of the Unit of Human Nutrition at the Department of Medical and Surgical Science, University Magna Graecia, Catanzaro, Italy. Dr Romeo received the Knut and Alice Wallenberg Academy fellowship in Medicine in 2017, the Novo Nordisk Foundation Excellence Project for Young Researchers within Endocrinology in 2014 and the Young Investigator Award from the European Atherosclerosis Society in 2008.

Main research

My research is focused on the human genetics of lipids and insulin resistance. At the University of Texas Southwestern Medical Center, I used a resequencing approach to show how common and rare mutations in angiopoietin-like proteins affect the metabolism of circulating triglycerides. I also performed a genome wide association study on the Dallas Heart Study population, which identified the patatin-like phospholipase domain-containing 3 (PNPLA3) I148M mutation as a determinant of hepatic steatosis. To date, this is the most widely replicated genetic mutation associated with this condition.

Together with my colleagues at the University of Cambridge, UK, I observed that the PNPLA3 148M mutation is associated with elevated transaminase levels (an index of hepatic damage) in obese adult and children but not in normal weight individuals. These findings suggest that obesity modulates signals arising from the genome, and indicate that the obese state is necessary to study traits highly correlated with obesity.

My research group at the Wallenberg Laboratory focuses on the role of genetic variants in modulating metabolic traits such as serum lipid levels, insulin resistance and liver fat accumulation. Our research field ranges from genetic association studies in large cohorts (including the Swedish Obese Subjects cohort) to molecular genetics of human mutations.

Since 2014, he has been responsible for the Lipid Clinic at the Department of Cardiology, Sahlgrenska University Hospital. The Lipid Clinic focuses on genetic testing and treatment of severe forms of hypercholesterolemia and hypertriglyceridemia. He is also a Faculty Member of the Unit of Human Nutrition at the Department of Medical and Surgical Science, University Magna Graecia, Catanzaro, Italy.

Dr Romeo received the Knut and Alice Wallenberg Academy fellowship in Medicine in 2017, the Novo Nordisk Foundation Excellence Project for Young Researchers within Endocrinology in 2014 and the Young Investigator Award from the European Atherosclerosis Society in 2008.
