Phosphatidylinositol-4, 5-bisphosphate 3-kinase, catalytic subunit gamma (PIK3CG) is a gene that encodes a protein that is a member of the pi3/pi4-kinase family. The protein functions in the phosphorylation of inositol rings and the association of adheren junctions. Missense mutations, nonsense mutations, silent mutations, and frameshift deletions are observed in cancers such as intestinal cancer, lung cancer, and skin cancer.

PIK3CG is altered in 2.98% of all cancers with non-small cell lung carcinoma, melanoma, colorectal adenocarcinoma, breast carcinoma, and malignant glioma having the greatest prevalence of alterations [3].

PIK3CG GENIE Cases - Top Diseases

The most common alterations in PIK3CG are PIK3CG Mutation (1.69%), PIK3CG Mutation (somatic) (1.69%), PIK3CG Amplification (0.11%), PIK3CG Loss (0.03%), and PIK3CG E615K (0.02%) [3].
