Figure 4. Mutation feature of C12orf75 in different tumors of TCGA and correlation of C12orf75 expression with immune infiltration level in BLCA, KIRP, and LIHC. The alteration frequency with mutation type (A) and mutation site (B) are displayed. (C) In BLCA, C12orf75 expression has a significant negative correlation with tumor purity, a significant positive correlation with infiltrating levels of CD8+ T cell, macrophage, neutrophil, and dendritic cell, and no relation with infiltrating levels of B cell and CD4+ T cell. (D) In KIRP, C12orf75 expression has no significant correlation with tumor purity, significant negative correlation with infiltrating levels of B cell and, CD8+ T cell, and no relation with infiltrating levels of CD4+ T cell, macrophage, neutrophil, and dendritic cell. (E) In LIHC, C12orf75 expression has no significant correlation with tumor purity and, significant positive correlation with infiltrating levels of B cell, CD8+ T cell, CD4+ T cell, macrophage, neutrophil, and dendritic cell.

P-values were corrected using the Benjamini-Hochberg method. p < 0.05 is considered as significant.
