Predominant deletions and mutations in WARS1 feature at the DNA level for many cancer types, including SKCM, cholangiocarcinoma (CHOL), BLCA, cervical squamous cell carcinoma, endocervical adenocarcinoma (CESC), esophageal carcinoma (ESCA), and colorectal cancers (Figure S1). This evidence concerns the gene WARS1 and cholangiocarcinoma.
