Genetic Risk Scores Link Diabetes Subgroups to Coronary Artery Disease

Understanding the Core Findings
Recent research from Lund University has identified a genetic connection between specific subgroups of diabetes and the risk of developing coronary artery disease (CAD). The study, published in *Diabetes Care*, highlights that genetic risk scores can predict CAD even before the onset of diabetes, particularly in individuals predisposed to a subgroup known as MOD (Metabolically Obese but Normal weight). This subgroup is characterized by obesity and early onset of type 2 diabetes, which significantly increases the risk of CAD, a common cardiovascular condition often linked to atherosclerosis.
Research Methodology and Population
The study analyzed data from 24,025 participants in the Malmö Diet Cancer (MDC) cohort, with 4,105 individuals developing diabetes during the follow-up period. Researchers utilized genetic risk scores derived from previous genome-wide association studies (GWAS) to assess the likelihood of participants developing both diabetes and CAD. This approach builds on earlier findings that categorized type 1 diabetes into one subgroup and type 2 diabetes into four distinct subgroups.
Implications for Early Detection
The findings suggest that early identification of individuals at high risk for both diabetes and CAD could enhance preventive measures. Andreas Edsfeldt, an associate professor in cardiology at Lund University, emphasized the importance of recognizing high-risk individuals before complications arise, such as myocardial infarction. The research team advocates for the use of genetic risk scores to facilitate tailored risk predictions, potentially delaying or preventing the onset of these diseases.
Criticism and Limitations
While the study presents promising insights, it is not without limitations. Mengyu Pan, a doctoral student involved in the research, noted that the study's population primarily consisted of individuals of European descent, which may limit the generalizability of the findings to more diverse populations. Future research is necessary to validate these results across different demographic groups.
Official Statements & Responses
Jiangming Sun, another associate professor at Lund University, stated, "Our DNA is inherited and largely stable across life, therefore genetic risk scores can help determine a person's risk of developing diabetes and coronary artery disease early in life." This sentiment underscores the potential of genetic assessments in preventive healthcare.
What's Next?
The research team plans to further investigate the biological mechanisms linking MOD to coronary artery disease. This future work aims to deepen the understanding of how genetic predispositions influence the development of CAD in individuals with diabetes, paving the way for improved prevention strategies.

- “Diabetes is a heterogeneous disease and the risk to develop coronary artery disease can differ greatly between individuals.” — Andreas Edsfeldt, Associate Professor in Cardiology, Lund University
- “I hope that genetic risk scores can be used to identify individuals who are at risk of developing diabetes and coronary artery disease long before early signs of disease.” — Andreas Edsfeldt, Associate Professor in Cardiology, Lund University
- “A limitation of our study is that it has been conducted on population studies where most participants are of European descent, which means that the findings may not be generalisable to other populations.” — Mengyu Pan, Doctoral Student in Bioinformatics, Lund University
