KMO and cancer: Researchers used cBioPortal to analyze the relationship between alterations in KMO gene amplification, mutation, and fusion and the relationship with cancer and found that the overall survival rate in clinical breast cancer patients with KMO gene alterations was lower than that in patients without KMO gene alterations and that high KMO expression was significantly correlated with shorter overall survival in breast cancer patients (Lai et al., 2021).
