Supplementary Figure 1 shows the expression levels of the nine genes, namely, CD4, CD8A, CD8B, MS4A1, CD68, CD274, MSLN, COL1A1, and COL5A1. Mutations in CD4, MS4A1, CD274, and COL1A1 were detected in at least one mesothelioma sample (Supplementary Figure 2). The gene discussed is CD8A; the disease is mesothelioma.
