Signal transducer and activator of transcription 3 (acute-phase response factor) (STAT3) is a gene that encodes a protein that functions in transcriptional activation. Missense mutations, nonsense mutations, silent mutations, frameshift deletions, and in-frame deletions and insertions are observed in cancers such as endometrial cancer, hematopoietic and lymphoid cancers, and stomach cancer.

STAT3 is altered in 1.29% of all cancers with colon adenocarcinoma, lung adenocarcinoma, endometrial endometrioid adenocarcinoma, breast invasive ductal carcinoma, and prostate adenocarcinoma having the greatest prevalence of alterations [3].

The most common alterations in STAT3 are STAT3 Mutation (1.03%), STAT3 Exon 21 Mutation (0.17%), STAT3 Exon 20 Mutation (0.13%), STAT3 Amplification (0.10%), and STAT3 Loss (0.05%) [3].
