Multiple endocrine neoplasia I (MEN1) is a gene that encodes menin. Menin is a tumor suppressor protein that functions in the inhibition of transcriptional activation. Missense mutations, nonsense mutations, silent mutations, frameshift insertions and deletions, and in-frame deletions and insertions are observed in cancers such as parathyroid cancer, retroperitoneal cancer, and thymus cancer.

MEN1 is altered in 1.59% of all cancers with pancreatic neuroendocrine neoplasm, breast invasive ductal carcinoma, colon adenocarcinoma, lung adenocarcinoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].
