By functionality, we grouped genes according to their function: regulator of energy metabolism (Gadd45a), apoptosis (Bcl2, Ier3), catabolic processes (Zfand2a), inflammation (Klkb1, Tnfrsf14), cell cycle control, and cancer (Csnk2a1, Cdc42, Rasa1, Prdx2, Tpr) (Table 1). The gene discussed is ZFAND2A; the disease is cancer.
