Additionally, a disease–gene association circos plot generated using RAW Graphs 2.0 (Figure 3d) showed tight linkage of hub DEGs such as DAPK2, DUSP3, IL6R, and UGP2 to cardiovascular comorbidities, including heart failure, diabetic retinopathy, cardiomyopathy, and pulmonary hypertension. The gene discussed is DUSP3; the disease is pulmonary hypertension.
