Mitogen-activated protein kinase kinase kinase 1, E3 ubiquitin protein ligase (MAP3K1) is a gene that encodes a protein that functions as a serine/threonine kinase in multiple cell signaling cascades. Missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions are observed in cancers such as breast cancer, endometrial cancer, and intestinal cancer.

MAP3K1 is altered in 3.05% of all cancers with breast invasive ductal carcinoma, lung adenocarcinoma, colon adenocarcinoma, invasive breast carcinoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].

MAP3K1 GENIE Cases - Top Diseases

The most common alterations in MAP3K1 are MAP3K1 Mutation (3.49%), MAP3K1 Loss (0.23%), MAP3K1 Amplification (0.06%), MAP3K1 R273Sfs*27 (0.06%), and MAP3K1 A5dup (0.05%) [3].
