Otherwise, a better prognosis was observed in patients with high YRDC expression compared to patients with low YRDC expression in only four tumors, including thymoma (THYM), STAD, COAD, and kidney renal clear cell carcinoma (KIRC) (p < 0.05, univariate Cox regression, Figures 3A and S2). Here, YRDC is linked to thymoma.
