The mutation frequency of CARM1 in the TCGA database was then examined using cBioPortal (10967 samples in 32 studies), and the obtained results revealed that OV and uterine corpus endometrial carcinoma (UCES) had a high mutation rate, with CARM1 mutations accounting for more than 7% of the total, as shown in Figure 4(a), followed by detecting 85 mutation sites (i.e., 65 missense, 7 truncating, and 13 fusion mutations) locating between amino acids 0 and 608, as shown in Figure 4(b). This evidence concerns the gene CARM1 and uterine corpus endometrial carcinoma.
