Signal transducer and activator of transcription 5A (STAT5A) is a gene that encodes a protein that functions as a transcription activator. Missense mutations, nonsense mutations, silent mutations, and frameshift deletions and insertions are observed in cancers such as endometrial cancer, intestinal cancer, and skin cancer.

STAT5A is altered in 0.85% of all cancers with colon adenocarcinoma, breast invasive ductal carcinoma, lung adenocarcinoma, prostate adenocarcinoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].

The most common alterations in STAT5A are STAT5A Mutation (0.55%), STAT5A Amplification (0.12%), STAT5A Loss (0.08%), STAT5A R152* (0.01%), and STAT5A R649W (0.01%) [3].
