In the gene co‐expression network, we observed that YRDC was associated with the expression of multiple immune cell signature genes at the pan‐cancer level, including T‐cell signature genes (CD3D, CD4, CD8A, CD8B), B‐cell signature genes (CD19, MS4A1), and multiple immunoglobulin genes (Figure 6A). The gene discussed is YRDC; the disease is cancer.
