Heat shock protein 90 kDa alpha (cytosolic), class A member 1 (HSP90AA1) is a gene that encodes a protein that functions as a molecular chaperone. The protein aids in the proper folding of target proteins by utilizing ATPase activity. Fusions, missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions and insertions are observed in cancers such as endometrial cancer, intestinal cancer, and skin cancer.

HSP90AA1 is altered in 2.12% of all cancers with breast invasive ductal carcinoma, lung adenocarcinoma, prostate adenocarcinoma, colon adenocarcinoma, and glioblastoma having the greatest prevalence of alterations [3].
