Beyond simply being overexpressed, FAM83A expression is an unfavourable prognostic gene in lung cancers35,36, and was documented as a prognostic biomarker (together with Keratin-19, Squamous carcinoma antigen (SCCA) and other proteins) capable of identifying circulating breast and lung cancer cells that predicted for shorter patient survival time37. The gene discussed is KRT19; the disease is lung cancer.
