Mitogen-activated protein kinase 1 (MAPK1) is a gene that encodes a protein that belongs to the MAP kinase family. The protein functions in several cell signaling processes such as proliferation, differentiation, transcriptional regulation, and cellular development. Missense, nonsense, and silent mutations are observed in cancers such as cervical cancer, endometrial cancer, and skin cancer.

MAPK1 is altered in 0.82% of all cancers with lung adenocarcinoma, colon adenocarcinoma, bladder urothelial carcinoma, endometrial endometrioid adenocarcinoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].

MAPK1 GENIE Cases - Top Diseases

The most common alterations in MAPK1 are MAPK1 Mutation (0.48%), MAPK1 Amplification (0.27%), MAPK1 Loss (0.09%), MAPK1 A7dup (0.08%), and MAPK1 E322K (0.07%) [3].
