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 0.75% of all cancers with lung adenocarcinoma, bladder urothelial carcinoma, colon adenocarcinoma, breast invasive ductal carcinoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].

The most common alterations in MAPK1 are MAPK1 Mutation (0.51%), MAPK1 Amplification (0.26%), MAPK1 A7dup (0.12%), MAPK1 Loss (0.07%), and MAPK1 E322K (0.07%) [3].
