Therefore, we chose four markers (cAMP-responsive element modulator (CREM), Glycine N-acyltransferase-like protein 3 (GLYATL3), ELMO/CED-12 domain containing 3 (ELMOD3), and Kruppel-like factor 9 (KLF9)), for which the CNA rates were less than 5% in BC, according to the cBioPortal database. This evidence concerns the gene GLYATL3 and breast cancer.
