Moreover CHAC1 was also found correlated with MSI in uterine carcinosarcoma (UCS) (P = .0087), PRAD (P = .025), cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) (P = 8.1e‐08), sarcoma (SARC) (P = .00067), BRCA (P = 5.1e‐08), COAD (P = .00037) and stomach adenocarcinoma (STAD) (0.00056) (Figure 3B) and correlated with TMB in CHOL (P = .0023), READ (P = .0055), LUAD (P = .00092), UCEC (P = .0011), KIRP (P = .0012), BRCA (P = 1.6e‐05) and COAD (P = .01) (Figure 3C). Here, CHAC1 is linked to endocervical adenocarcinoma.
