Genes annotated as inducers of wingless-type mouse mammary tumor virus (MMTV) integration site family members (Wnt) (for example, Norrie disease (Ndp)), several Wnt genes (for example, Wnt1) and all Wnt1-inducible signaling pathway proteins (Wisp1, Wisp2 and Wisp3) [30] completed the LE of Cluster_01-02. Here, CCN5 is linked to Norrie disease.
