Genes affected
NDP (HGNC:7678): (norrin cystine knot growth factor NDP) 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]
NDP-AS1 (HGNC:40395): (NDP antisense RNA 1)
