Mitogen-activated protein kinase kinase 2 (MAP2K2) is a gene that encodes a protein that is a member of the MAP kinase kinase family. The protein functions as a dual specificity protein kinase that regulates mitogen growth factor signal transduction by phosphorylating and activating MAPK1/ERK2 and MAPK2/ERK3. Missense and silent mutations are observed in cancers such as bone cancer, skin cancer, and stomach cancer.

MAP2K2 is altered in 0.86% of all cancers with colon adenocarcinoma, lung adenocarcinoma, cutaneous melanoma, breast invasive ductal carcinoma, and high grade ovarian serous adenocarcinoma having the greatest prevalence of alterations [3].

MAP2K2 GENIE Cases - Top Diseases

The most common alterations in MAP2K2 are MAP2K2 Mutation (0.63%), MAP2K2 Loss (0.15%), MAP2K2 Amplification (0.09%), MAP2K2 R231C (0.03%), and MAP2K2 Fusion (0.02%) [3].
