CSNK1A1 is known to influence tumor progression; however, its role as a tumor suppressor or oncogene is tumor type–dependent (Järås et al. 2014; Schittek and Sinnberg 2014; Lantermann et al. 2015; Cai et al. 2018), and CSNK1A1 has no known roles in PDAC. This evidence concerns the gene CSNK1A1 and neoplasm.
