Further analysis via the HPA database revealed that the expression frequency of FAM110B protein was 100% in tumor types such as thyroid cancer (4/4), colorectal cancer (12/12), head and neck cancer (4/4), renal cancer (12/12), testis cancer (10/10), and endometrial cancer (11/11) (Figure 1B). This evidence concerns the gene FAM110B and testicular cancer.
