In the 233 breast cancer cases in TCGA cohort, ZDHHC9 expression significantly predicted a poor prognosis (HR = 1.94, p = 0.046) (Fig. 6F) and was significantly negatively correlated with the infiltration of CD8 + T cells and NK cells (p < 0.001) (Fig. 6G). The gene discussed is ZDHHC9; the disease is breast cancer.
