Moreover, endometrial cancer also displays genetic mutations of diverse TSGs including TP53, CTNNB1, phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA), PTEN, and protein phosphatase 2 and regulatory subunit A alpha (PPP2R1A) (32–34). This evidence concerns the gene PPP2R1A and endometrial cancer.
