Figure 6. Relationship between SUSD4 expression and gene alterations. (A) The stacked bar plot shows the type and frequency of genetic changes in SUSD4. (B) Heatmap of correlation between methylation and copy number variation and SUSD4 expression. (C) Correlation between SUSD4 expression and CNV in THYM, CHOL, SARC and HNSC. (D) Correlation between SUSD4 expression and methylation in DLBC, GBM, THCA and USC. *p < 0.05, **p < 0.01, and ***p < 0.001. CNV, copy number variation. P-values were adjusted by false discovery rate (FDR) method.
