MDS1 and EVI1 complex locus (MECOM) is a gene that encodes a protein that functions as a transcriptional regulator and oncoprotein. The protein may also have roles in hematopoiesis, apoptosis, development, cell differentiation, and cell proliferation. Fusions, missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions are observed in cancers such as endometrial cancer, intestinal cancer, and skin cancer.

MECOM is altered in 1.67% of all cancers with melanoma, lung adenocarcinoma, colon adenocarcinoma, cutaneous melanoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].

MECOM GENIE Cases - Top Diseases

The most common alterations in MECOM are MECOM Mutation (2.90%), MECOM Amplification (0.46%), MECOM G614fs (0.18%), MECOM Fusion (0.05%), and MECOM E24K (0.06%) [3].
