Phosphatidylinositol-4, 5-bisphosphate 3-kinase, catalytic subunit delta (PIK3CD) is a gene that encodes a protein that function in the immune response and the phosphorylation of inositol lipids. Missense mutations, nonsense mutations, silent mutations, and frameshift insertions are observed in cancers such as endometrial cancer, intestinal cancer, and stomach cancer.

PIK3CD is altered in 1.74% of all cancers with colon adenocarcinoma, lung adenocarcinoma, breast invasive ductal carcinoma, endometrial endometrioid adenocarcinoma, and conventional glioblastoma multiforme having the greatest prevalence of alterations [3].
