The GEPIA platform was used to match the TCGA data with the normal tissue of the GTEx database, and the analysis showed that compared with the previous results, FAIM2 mRNA expression was also significantly low in adrenocortical carcinoma (ACC), testicular germ cell tumors (TGCT), and uterine varcinosarcoma (UCS) tumor tissues while thymoma (THYM) was high expression in tumor tissues (Figure 1B, C). This evidence concerns the gene FAIM2 and testicular germ cell tumor.
