Genetic alterations, including gene mutations and copy number alterations, are the potential factors impacting expression. We evaluated the genetic alterations of CDCAs with Oncoprinter from cBioportal and the impacts of CDCAs on PAAD patient survival23 (link), 24 (link). DNA methylation is another risk factor that affects the expression of CDCAs. The influence of DNA methylation on CDCA expression was assessed by DNMIVE25 (link), and the impact of a single-methylation CpG site on the OS of PAAD patients was analyzed by MethSurv26 (link).
