Mutations in PDE4DIP have been previously identified predominantly during sequencing of tumor samples, e.g., in prostate (Gupta et al., 2017), ovarian (Er et al., 2016), or lung cancer (Li et al., 2015), as well as in adult pineoblastoma (Snuderl et al., 2018). The gene discussed is PDE4DIP; the disease is lung cancer.
