Investigating shared genetic overlap of immune-mediated inflammatory diseases and cardiometabolic diseases

The study investigated genetic connections between immune-mediated inflammatory diseases and cardiometabolic diseases. Researchers found significant genetic correlations between rheumatoid arthritis and several cardiometabolic diseases including hypertension, coronary artery disease, heart failure, stroke, atrial fibrillation, and type 2 diabetes, with genetic correlation values ranging from 0.09 to 0.24. The analysis identified 164 independent genetic variants shared between rheumatoid arthritis and cardiometabolic diseases. The research revealed a shared genetic architecture and key immune-related biological pathways underlying rheumatoid arthritis and its associated cardiometabolic comorbidities. The identified genes and drugs provide opportunities for further therapeutic testing that could improve clinical management strategies.
