To further investigate the relationships among the SRP-DGs and risk of SSc-PH, we constructed a nomogram model using seven SRP-DGs (RPL32, RPS12, RPS14, RPS23, RPS3, RPS7, and SRP9) to predict the risk of pulmonary hypertension complications in patients with SSc (Figure 9A). This evidence concerns the gene UCN2 and pulmonary arterial hypertension.
