Signal transducer and activator of transcription 2 (STAT2) is a gene that encodes a member of the STAT protein family that functions as a transcription activator when translocated to the nucleus of a cell. Missense mutations, nonsense mutations, silent mutations, and frameshift deletions and insertions are observed in cancers such as cervical cancer, endometrial cancer, and intestinal cancer.

STAT2 is altered in 0.02% of all cancers with ovarian epithelial tumor having the greatest prevalence of alterations [3].

The most common alteration in STAT2 is STAT2-ERBB3 Fusion (0.02%) [3].
