NDP norrin cystine knot growth factor NDP

Gene ID: 4693, updated on 23-Jan-2022
Gene type: protein coding
Also known as: ND; EVR2; FEVR


This gene encodes a secreted protein with a cystein-knot motif that activates the Wnt/beta-catenin pathway. The protein forms disulfide-linked oligomers in the extracellular matrix. Mutations in this gene result in Norrie disease and X-linked exudative vitreoretinopathy. [provided by RefSeq, Feb 2009]
