V-maf avian musculoaponeurotic fibrosarcoma oncogene homolog (MAF) is a gene that encodes a protein that, depending on the binding site and binding partner, functions as a transcriptional activator or repressor. The protein is also involved in the regulation of cellular processes such as embryonic lens fiber cell development, increased T-cell susceptibility to apoptosis, and chondrocyte terminal differentiation. Fusions, missense mutations, nonsense mutations, silent mutations, and in-frame deletions are observed in cancers such as intestinal cancer, stomach cancer, and urinary tract cancer.

MAF is altered in 0.51% of all cancers with colon adenocarcinoma, lung adenocarcinoma, adenocarcinoma of unknown primary, endometrial endometrioid adenocarcinoma, and high grade ovarian serous adenocarcinoma having the greatest prevalence of alterations [3].

MAF GENIE Cases - Top Diseases

The most common alterations in MAF are MAF Loss (0.08%), MAF G145S (0.55%), MAF G204V (0.78%), MAF G238del (0.05%), and MAF A239T (0.03%) [3].
