Insulin receptor substrate 2 (IRS2) is a gene that encodes a protein of the same name that functions in regulating the effects of insulin-like growth factor 1 and insulin by mediating signaling between receptor tyrosine kinases and other associated proteins. Missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame insertions are observed in cancers such as esophageal cancer, intestinal cancer, and stomach cancer.

IRS2 is altered in 2.87% of all cancers with colon adenocarcinoma, lung adenocarcinoma, breast invasive ductal carcinoma, endometrial endometrioid adenocarcinoma, and prostate adenocarcinoma having the greatest prevalence of alterations [3].
