Associated Genetic Biomarkers
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 .
The most common alterations in MEN1 are MEN1 Mutation (0.97%), MEN1 Loss (0.12%), MEN1 Amplification (0.10%), MEN1 Fusion (0.06%), and MEN1 X267_splice (0.02%) .
MEN1 status serves as an inclusion eligibility criteria in 2 clinical trials, of which 2 are open and 0 are closed. Of the trials that contain MEN1 status as an inclusion criterion, 1 is phase 2 (1 open) and 1 is phase 3 (1 open).
Trials with MEN1 status in the inclusion eligibility criteria most commonly target bladder carcinoma, multiple endocrine neoplasia type 1, and urothelial carcinoma .
The most frequent alteration to serve as an inclusion eligibility criterion is MEN1 Mutation .
Observation, olaparib, and somatostatin analog therapy are the most frequent therapies in trials with MEN1 as an inclusion criteria .

MEN1 is an inclusion criterion in 1 clinical trial for multiple endocrine neoplasia type 1, of which 1 is open and 0 are closed. Of the trial that contains MEN1 status and multiple endocrine neoplasia type 1 as inclusion criteria, 1 is phase 3 (1 open) .
