We analyzed the correlation between COL5A1 and tumor stage and found that COL5A1 expression was significantly correlated to the tumor stage in 13 human tumors, including ACC, BLCA, CHOL, COAD, ESCA, HNSC, THCA, KICH, KIRC, KIRP, STAD, PAAD, and UVM (Figure 8; Figure S3). The gene discussed is COL5A1; the disease is neoplasm.
