As an oncogenic gene, ZFPM2-AS1 plays a role in retinoblastoma (Lyv et al., 2020), breast cancer (Zhao et al., 2020), small cell lung cancer (Yan et al., 2020), cervical cancer (Dai et al., 2020), esophageal squamous cell carcinoma (Sun and Wu, 2020), and other tumors. Here, ZFPM2 is linked to retinoblastoma.
