In uterine endometrioid carcinoma, the prevalent high mRNA expression of almost all CDCAs except CDCA7, the amplification of NUF2, CDCA3/5, the deep deletion of CDCA2 and the missense mutation of CDCA7 presented the most common altered genetic events. The gene discussed is CDCA7; the disease is endometrial endometrioid adenocarcinoma.
